 * @class Ext.Class

 * features made available by Ext.ClassManager. The only time you would use Ext.Class directly is to create an anonymous class.
 *
 * If you wish to create a class you should use {@link Ext#define Ext.define} which aliases
 * {@link Ext.ClassManager#create Ext.ClassManager.create} to enable namespacing and dynamic dependency resolution.
 *
 * Ext.Class is the factory and **not** the superclass of everything. For the base class that **all** Ext classes inherit

     *         }

     *
     * Within the class, this.name still has the default value of "Mr. Unknown". However, it's now publicly accessible
     * without sacrificing encapsulation, via setter and getter methods.
     *
     *     var jacky = new Person({
     *         name: "Jacky",
     *         age: 35

     *
     *     jacky.walk(10);             // alerts "Mr. Nguyen is walking 10 steps"
     *
     * Notice that we changed the class constructor to invoke this.initConfig() and pass in the provided config object.
     * Two key things happened:
     *
     *  - The provided config object when the class is instantiated is recursively merged with the default config object.
     *  - All corresponding setter methods are called with the merged values.
     *
     * Beside storing the given values, throughout the frameworks, setters generally have two key responsibilities:
     *
     *  - Filtering / validation / transformation of the given value before it's actually stored within the instance.
     *  - Notification (such as firing events) / post-processing after the value has been set, or changed from a
     *    previous value.
     *
     * By standardize this common pattern, the default generated setters provide two extra template methods that you
     * can put your own custom logics into, i.e: an "applyFoo" and "updateFoo" method for a "foo" config item, which are
     * executed before and after the value is actually set, respectively. Back to the example class, let's validate that
     * age must be a valid positive number, and fire an 'agechange' if the value is modified.
     *
     *     Ext.define('My.sample.Person', {
     *         config: {
     *             // ...
     *         },
     *
     *         constructor: {
     *             // ...
     *         },
     *
     *         applyAge: function(age) {
     *             if (typeof age !== 'number' || age < 0) {
     *                 console.warn("Invalid age, must be a positive number");
     *                 return;
     *             }
     *
     *             return age;
     *         },
     *
     *         updateAge: function(newAge, oldAge) {
     *             // age has changed from "oldAge" to "newAge"
     *             this.fireEvent('agechange', this, newAge, oldAge);
     *         }
     *
     *         // ...
     *     });
     *
     *     var jacky = new Person({
     *         name: "Jacky",
     *         age: 'invalid'
     *     });
     *
     *     alert(jacky.getAge());      // alerts 0
     *
     *     alert(jacky.setAge(-100));  // alerts 0
     *     alert(jacky.getAge());      // alerts 0
     *
     *     alert(jacky.setAge(35));    // alerts 0
     *     alert(jacky.getAge());      // alerts 35
     *
     * In other words, when leveraging the config feature, you mostly never need to define setter and getter methods
     * explicitly. Instead, "apply*" and "update*" methods should be implemented where necessary. Your code will be
     * consistent throughout and only contain the minimal logic that you actually care about.
     *
     * When it comes to inheritance, the default config of the parent class is automatically, recursively merged with
     * the child's default config. The same applies for mixins.

/**
 * @class  Ext.ClassManager
 * @author Jacky Nguyen <jacky@sencha.com>
 *
 * Ext.ClassManager manages all classes and handles mapping from string class name to
 * actual class objects throughout the whole framework. It is not generally accessed directly, rather through
 * these convenient shorthands:
 *
 * - {@link Ext#define Ext.define}
 * - {@link Ext.ClassManager#create Ext.create}
 * - {@link Ext#widget Ext.widget}
 * - {@link Ext#getClass Ext.getClass}
 * - {@link Ext#getClassName Ext.getClassName}
 *
 * For more information about Sencha Touch's Class System, please check out the [class system guide](../../../core_concepts/class_system.html).
 * 
 * ## Basic syntax:
 *
 *     Ext.define(className, properties);
 *
 * in which `properties` is an object represent a collection of properties that apply to the class. See
 * {@link Ext.ClassManager#create} for more detailed instructions.
 *
 *     @example
 *     Ext.define('Person', {
 *          name: 'Unknown',
 *
 *          constructor: function(name) {
 *              if (name) {
 *                  this.name = name;
 *              }
 *
 *              return this;
 *          },
 *
 *          eat: function(foodType) {
 *              alert("I'm eating: " + foodType);
 *
 *              return this;
 *          }
 *     });
 *
 *     var aaron = new Person("Aaron");
 *     aaron.eat("Sandwich"); // alert("I'm eating: Sandwich");
 *
 * Ext.Class has a powerful set of extensible {@link Ext.Class#registerPreprocessor pre-processors} which takes care of
 * everything related to class creation, including but not limited to inheritance, mixins, configuration, statics, etc.
 *
 * ## Inheritance:
 *
 *     Ext.define('Developer', {
 *          extend: 'Person',
 *
 *          constructor: function(name, isGeek) {
 *              this.isGeek = isGeek;
 *
 *              // Apply a method from the parent class' prototype
 *              this.callParent([name]);
 *
 *              return this;
 *
 *          },
 *
 *          code: function(language) {
 *              alert("I'm coding in: " + language);
 *
 *              this.eat("Bugs");
 *
 *              return this;
 *          }
 *     });
 *
 *     var jacky = new Developer("Jacky", true);
 *     jacky.code("JavaScript"); // alert("I'm coding in: JavaScript");
 *                               // alert("I'm eating: Bugs");
 *
 * See {@link Ext.Base#callParent} for more details on calling superclass' methods
 *
 * ## Mixins:
 *
 *     Ext.define('CanPlayGuitar', {
 *          playGuitar: function() {
 *             alert("F#...G...D...A");
 *          }
 *     });
 *
 *     Ext.define('CanComposeSongs', {

 *              alert("I'm on the highway to hell...");
 *          }
 *     });
 *
 *     Ext.define('Musician', {
 *          extend: 'Person',
 *
 *          mixins: {

 *              canComposeSongs: 'CanComposeSongs',
 *              canSing: 'CanSing'
 *          }
 *     });
 *
 *     Ext.define('CoolPerson', {
 *          extend: 'Person',

 *              canSing: 'CanSing'
 *          },
 *
 *          sing: function() {
 *              alert("Ahem...");
 *
 *              this.mixins.canSing.sing.call(this);
 *
 *              alert("[Playing guitar at the same time...]");
 *
 *              this.playGuitar();
 *          }
 *     });
 *
 *     var me = new CoolPerson("Jacky");
 *
 *     me.sing(); // alert("Ahem...");
 *                // alert("I'm on the highway to hell...");
 *                // alert("[Playing guitar at the same time...]");
 *                // alert("F#...G...D...A");
 *
 * ## Config:
 *
 *     Ext.define('SmartPhone', {
 *          config: {
 *              hasTouchScreen: false,
 *              operatingSystem: 'Other',
 *              price: 500
 *          },
 *
 *          isExpensive: false,
 *
 *          constructor: function(config) {
 *              this.initConfig(config);
 *
 *              return this;
 *          },
 *
 *          applyPrice: function(price) {
 *              this.isExpensive = (price > 500);
 *
 *              return price;
 *          },
 *
 *          applyOperatingSystem: function(operatingSystem) {
 *              if (!(/^(iOS|Android|BlackBerry)$/i).test(operatingSystem)) {
 *                  return 'Other';
 *              }
 *
 *              return operatingSystem;
 *          }
 *     });
 *
 *     var iPhone = new SmartPhone({
 *          hasTouchScreen: true,
 *          operatingSystem: 'iOS'
 *     });
 *
 *     iPhone.getPrice(); // 500;
 *     iPhone.getOperatingSystem(); // 'iOS'
 *     iPhone.getHasTouchScreen(); // true;
 *
 *     iPhone.isExpensive; // false;
 *     iPhone.setPrice(600);
 *     iPhone.getPrice(); // 600
 *     iPhone.isExpensive; // true;
 *
 *     iPhone.setOperatingSystem('AlienOS');
 *     iPhone.getOperatingSystem(); // 'Other'
 *
 * ## Statics:
 *
 *     Ext.define('Computer', {
 *          statics: {
 *              factory: function(brand) {
 *                 // 'this' in static methods refer to the class itself
 *                  return new this(brand);
 *              }
 *          },
 *
 *          constructor: function() { }
 *     });
 *
 *     var dellComputer = Computer.factory('Dell');
 *
 * Also see {@link Ext.Base#statics} and {@link Ext.Base#self} for more details on accessing
 * static properties within class methods

         *
         * To defines an override, include the `override` property. The content of an
         * override is aggregated with the specified class in order to extend or modify
         * that class. This can be as simple as setting default property values or it can
         * extend and/or replace methods. This can also extend the statics of the class.
         *
         * One use for an override is to break a large class into manageable pieces.
         *
         *      // File: /src/app/Panel.js
         *      Ext.define('My.app.Panel', {
         *          extend: 'Ext.panel.Panel',
         *          requires: [
         *              'My.app.PanelPart2',
         *              'My.app.PanelPart3'
         *          ],
         *
         *          constructor: function (config) {
         *              this.callParent(arguments); // calls Ext.panel.Panel's constructor
         *              // ...
         *          },
         *
         *          statics: {
         *              method: function () {
         *                  return 'abc';
         *              }
         *          }
         *      });
         *
         *      // File: /src/app/PanelPart2.js
         *      Ext.define('My.app.PanelPart2', {
         *          override: 'My.app.Panel',
         *
         *          constructor: function (config) {
         *              this.callParent(arguments); // calls My.app.Panel's constructor
         *              // ...
         *          }
         *      });
         *
         * Another use for an override is to provide optional parts of classes that can be
         * independently required. In this case, the class may even be unaware of the
         * override altogether.
         *
         *      Ext.define('My.ux.CoolTip', {
         *          override: 'Ext.tip.ToolTip',
         *
         *          constructor: function (config) {
         *              this.callParent(arguments); // calls Ext.tip.ToolTip's constructor
         *              // ...
         *          }
         *      });
         *
         * The above override can now be required as normal.
         *
         *      Ext.define('My.app.App', {
         *          requires: [
         *              'My.ux.CoolTip'
         *          ]
         *      });
         *
         * Overrides can also contain statics:
         *
         *      Ext.define('My.app.BarMod', {
         *          override: 'Ext.foo.Bar',
         *
         *          statics: {
         *              method: function (x) {
         *                  return this.callParent([x * 2]); // call Ext.foo.Bar.method
         *              }
         *          }
         *      });
         *
         * __IMPORTANT:__ An override is only included in a build if the class it overrides is
         * required. Otherwise, the override, like the target class, is not included.
         *
         * @param {String} className The class name to create in string dot-namespaced format, for example:
         * 'My.very.awesome.Class', 'FeedViewer.plugin.CoolPager'
         *
         * It is highly recommended to follow this simple convention:
         *  - The root and the class name are 'CamelCased'
         *  - Everything else is lower-cased
         *
         * @param {Object} data The key - value pairs of properties to apply to this class. Property names can be of
         * any valid strings, except those in the reserved listed below:

/**
 * @class Ext.Loader
 *
 * @author Jacky Nguyen <jacky@sencha.com>
 * @docauthor Jacky Nguyen <jacky@sencha.com>
 *
 * Ext.Loader is the heart of the new dynamic dependency loading capability in Ext JS 4+. It is most commonly used
 * via the {@link Ext#require} shorthand. Ext.Loader supports both asynchronous and synchronous loading
 * approaches, and leverage their advantages for the best development flow.
 * We'll discuss about the pros and cons of each approach.
 *
 * __Note:__ The Loader is only enabled by default in development versions of the library (eg sencha-touch-debug.js). To
 * explicitly enable the loader, use `Ext.Loader.setConfig({ enabled: true });` before the start of your script.
 *
 * ## Asynchronous Loading
 *
 * - Advantages:
 * 	+ Cross-domain
 * 	+ No web server needed: you can run the application via the file system protocol (i.e: `file://path/to/your/index
 *  .html`)
 * 	+ Best possible debugging experience: error messages come with the exact file name and line number
 *
 * - Disadvantages:
 * 	+ Dependencies need to be specified before-hand
 *
 * ### Method 1: Explicitly include what you need: ###
 *
 *     // Syntax
 *     // Ext.require({String/Array} expressions);
 *
 *     // Example: Single alias
 *     Ext.require('widget.window');
 *
 *     // Example: Single class name
 *     Ext.require('Ext.window.Window');
 *
 *     // Example: Multiple aliases / class names mix
 *     Ext.require(['widget.window', 'layout.border', 'Ext.data.Connection']);
 *
 *     // Wildcards
 *     Ext.require(['widget.*', 'layout.*', 'Ext.data.*']);
 *
 * ### Method 2: Explicitly exclude what you don't need: ###
 *
 *     // Syntax: Note that it must be in this chaining format.
 *     // Ext.exclude({String/Array} expressions)
 *     //    .require({String/Array} expressions);
 *
 *     // Include everything except Ext.data.*
 *     Ext.exclude('Ext.data.*').require('*');
 *
 *     // Include all widgets except widget.checkbox*,
 *     // which will match widget.checkbox, widget.checkboxfield, widget.checkboxgroup, etc.
 *     Ext.exclude('widget.checkbox*').require('widget.*');
 *
 * # Synchronous Loading on Demand #
 *
 * - *Advantages:*
 * 	+ There's no need to specify dependencies before-hand, which is always the convenience of including ext-all.js
 *  before
 *
 * - *Disadvantages:*
 * 	+ Not as good debugging experience since file name won't be shown (except in Firebug at the moment)
 * 	+ Must be from the same domain due to XHR restriction
 * 	+ Need a web server, same reason as above
 *
 * There's one simple rule to follow: Instantiate everything with Ext.create instead of the `new` keyword
 *
 *     Ext.create('widget.window', {}); // Instead of new Ext.window.Window({...});
 *
 *     Ext.create('Ext.window.Window', {}); // Same as above, using full class name instead of alias
 *
 *     Ext.widget('window', {}); // Same as above, all you need is the traditional `xtype`
 *
 * Behind the scene, {@link Ext.ClassManager} will automatically check whether the given class name / alias has already
 *  existed on the page. If it's not, Ext.Loader will immediately switch itself to synchronous mode and automatic load the given
 *  class and all its dependencies.
 *
 * # Hybrid Loading - The Best of Both Worlds #
 *
 * It has all the advantages combined from asynchronous and synchronous loading. The development flow is simple:
 *
 * ### Step 1: Start writing your application using synchronous approach. ###
 * Ext.Loader will automatically fetch all dependencies on demand as they're
 * needed during run-time. For example:
 *
 *     Ext.onReady(function(){
 *         var window = Ext.createWidget('window', {
 *             width: 500,
 *             height: 300,
 *             layout: {
 *                 type: 'border',
 *                 padding: 5
 *             },
 *             title: 'Hello Dialog',
 *             items: [{
 *                 title: 'Navigation',
 *                 collapsible: true,
 *                 region: 'west',
 *                 width: 200,
 *                 html: 'Hello',
 *                 split: true
 *             }, {
 *                 title: 'TabPanel',
 *                 region: 'center'
 *             }]
 *         });
 *
 *         window.show();
 *     });
 *
 * ### Step 2: Along the way, when you need better debugging ability, watch the console for warnings like these: ###
 *
 *     [Ext.Loader] Synchronously loading 'Ext.window.Window'; consider adding Ext.require('Ext.window.Window') before your application's code
 *     ClassManager.js:432
 *     [Ext.Loader] Synchronously loading 'Ext.layout.container.Border'; consider adding Ext.require('Ext.layout.container.Border') before your application's code
 *
 * Simply copy and paste the suggested code above `Ext.onReady`, i.e:
 *
 *     Ext.require('Ext.window.Window');
 *     Ext.require('Ext.layout.container.Border');
 *
 *     Ext.onReady(function () {
 *         // ...
 *     });
 *
 * Everything should now load via asynchronous mode.
 *
 * # Deployment #
 *
 * It's important to note that dynamic loading should only be used during development on your local machines.
 * During production, all dependencies should be combined into one single JavaScript file. Ext.Loader makes
 * the whole process of transitioning from / to between development / maintenance and production as easy as
 * possible. Internally {@link Ext.Loader#history Ext.Loader.history} maintains the list of all dependencies your application
 * needs in the exact loading sequence. It's as simple as concatenating all files in this array into one,
 * then include it on top of your application.
 * 
 * @singleton

 *
 * Ext is the global namespace for the whole Sencha Touch framework. Every class, function and configuration for the
 * whole framework exists under this single global variable. The Ext singleton itself contains a set of useful helper
 * functions (like {@link #apply}, {@link #min} and others), but most of the framework that you use day to day exists
 * in specialized classes (for example {@link Ext.Panel}, {@link Ext.Carousel} and others).
 *
 * If you are new to Sencha Touch we recommend starting with the [Getting Started Guide][../../../getting_started/getting_started.html] to
 * get a feel for how the framework operates. After that, use the more focused guides on subjects like panels, forms and data
 * to broaden your understanding. 
 *
 * The functions listed below are mostly utility functions used internally by many of the classes shipped in the
 * framework, but also often useful in your own apps.
 *
 * A method that is crucial to beginning your application is {@link #setup Ext.setup}. Please refer to it's documentation, or the
 * [Getting Started Guide][../../../getting_started/getting_started.html] as a reference on beginning your application.

     * Ext.setup() is the entry-point to initialize a Sencha Touch application. Note that if your application makes
     * use of MVC architecture, use {@link Ext#application} instead.
     *
     * This method accepts one single argument in object format. The most basic use of Ext.setup() is as follows:
     *
     *     Ext.setup({
     *         onReady: function() {
     *             // ...
     *         }
     *     });
     *
     * This sets up the viewport, initializes the event system, instantiates a default animation runner, and a default
     * logger (during development). When all of that is ready, it invokes the callback function given to the `onReady` key.
     *
     * The default scope (`this`) of `onReady` is the main viewport. By default the viewport instance is stored in
     * {@link Ext.Viewport}. For example, this snippet adds a 'Hello World' button that is centered on the screen:
     *
     *     Ext.setup({
     *         onReady: function() {
     *             this.add({
     *                 xtype: 'button',
     *                 centered: true,
     *                 text: 'Hello world!'
     *             }); // Equivalent to Ext.Viewport.add(...)
     *         }
     *     });
     *
     * @param {Object} config An object with the following config options:
     *
     * @param {Function} config.onReady
     * A function to be called when the application is ready. Your application logic should be here.
     *
     * @param {Object} config.viewport
     * A custom config object to be used when creating the global {@link Ext.Viewport} instance. Please refer to the
     * {@link Ext.Viewport} documentation for more information.
     *
     *     Ext.setup({
     *         viewport: {
     *             width: 500,
     *             height: 500
     *         },
     *         onReady: function() {
     *             // ...
     *         }
     *     });
     *
     * @param {String/Object} config.icon
     * Specifies a set of URLs to the application icon for different device form factors. This icon is displayed
     * when the application is added to the device's Home Screen.
     *
     *     Ext.setup({
     *         icon: {
     *             57: 'resources/icons/Icon.png',
     *             72: 'resources/icons/Icon~ipad.png',
     *             114: 'resources/icons/Icon@2x.png',
     *             144: 'resources/icons/Icon~ipad@2x.png'
     *         },
     *         onReady: function() {
     *             // ...
     *         }
     *     });
     *
     * Each key represents the dimension of the icon as a square shape. For example: '57' is the key for a 57 x 57
     * icon image. Here is the breakdown of each dimension and its device target:
     *
     * - 57: Non-retina iPhone, iPod touch, and all Android devices
     * - 72: Retina iPhone and iPod touch
     * - 114: Non-retina iPad (first and second generation)
     * - 144: Retina iPad (third generation)
     *
     * Note that the dimensions of the icon images must be exactly 57x57, 72x72, 114x114 and 144x144 respectively.
     *
     * It is highly recommended that you provide all these different sizes to accommodate a full range of
     * devices currently available. However if you only have one icon in one size, make it 57x57 in size and
     * specify it as a string value. This same icon will be used on all supported devices.

     * Please note that there's no automatic fallback mechanism for the startup images. In other words, if you don't specify
     * a valid image for a certain device, nothing will be displayed while the application is being launched on that device.
     *
     * @param {Boolean} config.isIconPrecomposed
     * True to not having a glossy effect added to the icon by the OS, which will preserve its exact look. This currently
     * only applies to iOS devices.
     *
     * @param {String} config.statusBarStyle
     * The style of status bar to be shown on applications added to the iOS home screen. Valid options are:
     *
     * * `default`
     * * `black`
     * * `black-translucent`
     *
     * @param {String[]} config.requires

     *
     * @param {Object} config.eventPublishers
     * Sencha Touch, by default, includes various {@link Ext.event.recognizer.Recognizer} subclasses to recognize events fired

     * {@link Ext.event.recognizer.Recognizer}.
     *
     * To change the default recognizers, you can use the following syntax:
     *
     *     Ext.setup({
     *         eventPublishers: {
     *             touchGesture: {

     *                     swipe: {
     *                         // this will include both vertical and horizontal swipe recognizers
     *                         xclass: 'Ext.event.recognizer.Swipe'
     *                     }

     *             // ...
     *         }
     *     });
     *
     * You can also disable recognizers using this syntax:
     *
     *     Ext.setup({
     *         eventPublishers: {
     *             touchGesture: {

     * - 768x1004: Non-retina iPad (first and second generation) in portrait orientation
     * - 748x1024: Non-retina iPad (first and second generation) in landscape orientation
     * - 1536x2008: Retina iPad (third generation) in portrait orientation
     * - 1496x2048: Retina iPad (third generation) in landscape orientation
     *
     * Please note that there's no automatic fallback mechanism for the startup images. In other words, if you don't specify
     * a valid image for a certain device, nothing will be displayed while the application is being launched on that device.
     *
     * @param {Boolean} config.isIconPrecomposed
     * True to not having a glossy effect added to the icon by the OS, which will preserve its exact look. This currently
     * only applies to iOS devices.
     *
     * @param {String} config.statusBarStyle
     * The style of status bar to be shown on applications added to the iOS home screen. Valid options are:
     *
     * * `default`
     * * `black`
     * * `black-translucent`
     *
     * @param {String[]} config.requires
     * An array of required classes for your application which will be automatically loaded if {@link Ext.Loader#enabled} is set
     * to `true`. Please refer to {@link Ext.Loader} and {@link Ext.Loader#require} for more information.
     *
     *     Ext.application({
     *         requires: ['Ext.Button', 'Ext.tab.Panel'],
     *         launch: function() {
     *             // ...
     *         }
     *     });
     *
     * @param {Object} config.eventPublishers
     * Sencha Touch, by default, includes various {@link Ext.event.recognizer.Recognizer} subclasses to recognize events fired
     * in your application. The list of default recognizers can be found in the documentation for {@link Ext.event.recognizer.Recognizer}.
     *
     * To change the default recognizers, you can use the following syntax:
     *
     *     Ext.application({
     *         eventPublishers: {
     *             touchGesture: {
     *                 recognizers: {
     *                     swipe: {
     *                         // this will include both vertical and horizontal swipe recognizers
     *                         xclass: 'Ext.event.recognizer.Swipe'
     *                     }
     *                 }
     *             }
     *         },
     *         launch: function() {
     *             // ...
     *         }
     *     });
     *
     * You can also disable recognizers using this syntax:
     *
     *     Ext.application({
     *         eventPublishers: {
     *             touchGesture: {
     *                 recognizers: {
     *                     swipe: null,
     *                     pinch: null,
     *                     rotate: null
     *                 }
     *             }
     *         },
     *         launch: function() {
     *             // ...
     *         }
     *     });
     *
     * @param {Function} config.onUpdated
     * This function will execute once the production microloader determines there are updates to the application and has
     * merged the updates into the application. You can then alert the user there was an update and can then reload
     * the application to execute the updated application.
     *
     *     Ext.application({
     *         onUpdated : function() {
     *             Ext.Msg.confirm(
     *                 'Application Update',
     *                 'This application has just successfully been updated to the latest version. Reload now?',

/**
 * @class Ext.DomQuery
 * @alternateClassName Ext.core.DomQuery
 * @extend Ext.dom.Query
 * @singleton
 *
 * Provides functionality to select elements on the page based on a CSS selector. Delegates to
 * document.querySelectorAll. More information can be found at
 * [http://www.w3.org/TR/css3-selectors/](http://www.w3.org/TR/css3-selectors/)
 *
 * All selectors, attribute filters and pseudos below can be combined infinitely in any order. For example
 * `div.foo:nth-child(odd)[@foo=bar].bar:first` would be a perfectly valid selector.
 *
 * ## Element Selectors:
 *
 * * \* any element
 * * E an element with the tag E
 * * E F All descendant elements of E that have the tag F
 * * E > F or E/F all direct children elements of E that have the tag F
 * * E + F all elements with the tag F that are immediately preceded by an element with the tag E
 * * E ~ F all elements with the tag F that are preceded by a sibling element with the tag E
 *
 * ## Attribute Selectors:
 *
 * The use of @ and quotes are optional. For example, div[@foo='bar'] is also a valid attribute selector.
 *
 * * E[foo] has an attribute "foo"
 * * E[foo=bar] has an attribute "foo" that equals "bar"
 * * E[foo^=bar] has an attribute "foo" that starts with "bar"
 * * E[foo$=bar] has an attribute "foo" that ends with "bar"
 * * E[foo*=bar] has an attribute "foo" that contains the substring "bar"
 * * E[foo%=2] has an attribute "foo" that is evenly divisible by 2
 * * E[foo!=bar] has an attribute "foo" that does not equal "bar"
 *
 * ## Pseudo Classes:
 *
 * * E:first-child E is the first child of its parent
 * * E:last-child E is the last child of its parent
 * * E:nth-child(n) E is the nth child of its parent (1 based as per the spec)
 * * E:nth-child(odd) E is an odd child of its parent
 * * E:nth-child(even) E is an even child of its parent
 * * E:only-child E is the only child of its parent
 * * E:checked E is an element that is has a checked attribute that is true (e.g. a radio or checkbox)
 * * E:first the first E in the resultset
 * * E:last the last E in the resultset
 * * E:nth(n) the nth E in the resultset (1 based)
 * * E:odd shortcut for :nth-child(odd)
 * * E:even shortcut for :nth-child(even)
 * * E:not(S) an E element that does not match simple selector S
 * * E:has(S) an E element that has a descendant that matches simple selector S
 * * E:next(S) an E element whose next sibling matches simple selector S
 * * E:prev(S) an E element whose previous sibling matches simple selector S
 * * E:any(S1|S2|S2) an E element which matches any of the simple selectors S1, S2 or S3//\\
 *
 * ## CSS Value Selectors:
 *
 * * E{display=none} CSS value "display" that equals "none"
 * * E{display^=none} CSS value "display" that starts with "none"
 * * E{display$=none} CSS value "display" that ends with "none"
 * * E{display*=none} CSS value "display" that contains the substring "none"
 * * E{display%=2} CSS value "display" that is evenly divisible by 2
 * * E{display!=none} CSS value "display" that does not equal "none"

/**
 * @class Ext.DomHelper
 * @alternateClassName Ext.dom.Helper
 * @singleton
 *
 * The DomHelper class provides a layer of abstraction from DOM and transparently supports creating elements via DOM or
 * using HTML fragments. It also has the ability to create HTML fragment templates from your DOM building code.
 *
 * ## DomHelper element specification object
 *
 * A specification object is used when creating elements. Attributes of this object are assumed to be element
 * attributes, except for 4 special attributes:
 *
 * * **tag**: The tag name of the element
 * * **children (or cn)**: An array of the same kind of element definition objects to be created and appended. These
 * can be nested as deep as you want.
 * * **cls**: The class attribute of the element. This will end up being either the "class" attribute on a HTML
 * fragment or className for a DOM node, depending on whether DomHelper is using fragments or DOM.
 * * **html**: The innerHTML for the element
 *
 * ## Insertion methods
 *
 * Commonly used insertion methods:
 *
 * * {@link #append}
 * * {@link #insertBefore}
 * * {@link #insertAfter}
 * * {@link #overwrite}
 * * {@link #insertHtml}
 *
 * ## Example
 *
 * This is an example, where an unordered list with 3 children items is appended to an existing element with id
 * 'my-div':
 *
 *     var dh = Ext.DomHelper; // create shorthand alias
 *     // specification object
 *     var spec = {
 *         id: 'my-ul',
 *         tag: 'ul',
 *         cls: 'my-list',
 *         // append children after creating
 *         children: [     // may also specify 'cn' instead of 'children'
 *             {tag: 'li', id: 'item0', html: 'List Item 0'},
 *             {tag: 'li', id: 'item1', html: 'List Item 1'},
 *             {tag: 'li', id: 'item2', html: 'List Item 2'}
 *         ]
 *     };
 *     var list = dh.append(
 *         'my-div', // the context element 'my-div' can either be the id or the actual node
 *         spec      // the specification object
 *     );
 *
 * Element creation specification parameters in this class may also be passed as an Array of specification objects.
 * This can be used to insert multiple sibling nodes into an existing container very efficiently. For example, to add
 * more list items to the example above:
 *
 *     dh.append('my-ul', [
 *         {tag: 'li', id: 'item3', html: 'List Item 3'},
 *         {tag: 'li', id: 'item4', html: 'List Item 4'}
 *     ]);
 *
 * ## Templating
 *
 * The real power is in the built-in templating. Instead of creating or appending any elements, createTemplate returns
 * a Template object which can be used over and over to insert new elements. Revisiting the example above, we could
 * utilize templating this time:
 *
 *     // create the node
 *     var list = dh.append('my-div', {tag: 'ul', cls: 'my-list'});
 *     // get template
 *     var tpl = dh.createTemplate({tag: 'li', id: 'item{0}', html: 'List Item {0}'});
 *
 *     for(var i = 0; i < 5; i++){
 *         tpl.append(list, i); // use template to append to the actual node
 *     }
 *
 * An example using a template:
 *
 *     var html = '"{0}" href="{1}" class="nav">{2}';
 *
 *     var tpl = new Ext.DomHelper.createTemplate(html);
 *     tpl.append('blog-roll', ['link1', 'http://www.tommymaintz.com/', "Tommy's Site"]);
 *     tpl.append('blog-roll', ['link2', 'http://www.avins.org/', "Jamie's Site"]);
 *
 * The same example using named parameters:
 *
 *     var html = '"{id}" href="{url}" class="nav">{text}';
 *
 *     var tpl = new Ext.DomHelper.createTemplate(html);
 *     tpl.append('blog-roll', {
 *         id: 'link1',
 *         url: 'http://www.tommymaintz.com/',
 *         text: "Tommy's Site"
 *     });
 *     tpl.append('blog-roll', {
 *         id: 'link2',
 *         url: 'http://www.avins.org/',
 *         text: "Jamie's Site"
 *     });
 *
 * ## Compiling Templates
 *
 * Templates are applied using regular expressions. The performance is great, but if you are adding a bunch of DOM
 * elements using the same template, you can increase performance even further by "compiling" the template. The way
 * "compile()" works is the template is parsed and broken up at the different variable points and a dynamic function is
 * created and eval'ed. The generated function performs string concatenation of these parts and the passed variables
 * instead of using regular expressions.
 *
 *     var html = '"{id}" href="{url}" class="nav">{text}';
 *
 *     var tpl = new Ext.DomHelper.createTemplate(html);
 *     tpl.compile();
 *
 *     // ... use template like normal
 *
 * ## Performance Boost
 *
 * DomHelper will transparently create HTML fragments when it can. Using HTML fragments instead of DOM can
 * significantly boost performance.
 *
 * Element creation specification parameters may also be strings. If useDom is false, then the string is used as
 * innerHTML. If useDom is true, a string specification results in the creation of a text node. Usage:
 *
 *     Ext.DomHelper.useDom = true; // force it to use DOM; reduces performance
 *

/**
 * Mixin that provides a common interface for publishing events. Classes using this mixin can use the {@link #fireEvent}
 * and {@link #fireAction} methods to notify listeners of events on the class.
 *
 * Classes can also define a {@link #listeners} config to add an event handler to the current object. See
 * {@link #addListener} for more details.
 *
 * ## Example
 *
 *     Ext.define('Employee', {
 *         mixins: ['Ext.mixin.Observable'],
 *
 *         config: {
 *             fullName: ''
 *         },
 *
 *         constructor: function(config) {
 *             this.initConfig(config);  // We need to initialize the config options when the class is instantiated
 *         },
 *
 *         quitJob: function() {
 *              this.fireEvent('quit');
 *         }
 *     });
 *
 *     var newEmployee = Ext.create('Employee', {
 *
 *         fullName: 'Ed Spencer',
 *
 *         listeners: {
 *             quit: function() { // This function will be called when the 'quit' event is fired
 *                 // By default, "this" will be the object that fired the event.
 *                 console.log(this.getFullName() + " has quit!");
 *             }
 *         }
 *     });
 *
 *     newEmployee.quitJob(); // Will log 'Ed Spencer has quit!'

    /**
     * Appends an event handler to this object. You can review the available handlers by looking at the 'events'
     * section of the documentation for the component you are working with.
     *
     * ## Combining Options
     *
     * Using the options argument, it is possible to combine different types of listeners:
     *
     * A delayed, one-time listener:
     *
     *     container.addListener('tap', this.handleTap, this, {
     *         single: true,
     *         delay: 100
     *     });
     *
     * ## Attaching multiple handlers in 1 call
     *
     * The method also allows for a single argument to be passed which is a config object containing properties which
     * specify multiple events. For example:
     *
     *     container.addListener({
     *         tap  : this.onTap,
     *         swipe: this.onSwipe,
     *
     *         scope: this // Important. Ensure "this" is correct during handler execution
     *     });
     *
     * One can also specify options for each event handler separately:
     *
     *     container.addListener({
     *         tap  : { fn: this.onTap, scope: this, single: true },
     *         swipe: { fn: button.onSwipe, scope: button }
     *     });
     *
     * See the [Events Guide](../../../core_concepts/events.html) for more.
     *
     * @param {String/String[]/Object} eventName The name of the event to listen for. May also be an object who's property names are
     * event names.
     * @param {Function/String} [fn] The method the event invokes.  Will be called with arguments given to
     * {@link #fireEvent} plus the `options` parameter described below.
     * @param {Object} [scope] The scope (`this` reference) in which the handler function is executed. **If
     * omitted, defaults to the object which fired the event.**
     * @param {Object} [options] An object containing handler configuration.
     *
     * This object may contain any of the following properties:

     * @param {Object} [options.scope] The scope (`this` reference) in which the handler function is executed. If omitted, defaults to the object
     * which fired the event.
     * @param {Number} [options.delay] The number of milliseconds to delay the invocation of the handler after the event fires.
     * @param {Boolean} [options.single] `true` to add a handler to handle just the next firing of the event, and then remove itself.
     * @param {String} [options.order=current] The order of when the listener should be added into the listener queue.
     *
     * If you set an order of `before` and the event you are listening to is preventable, you can return `false` and it will stop the event.

/**
 * A template class that supports advanced functionality like:
 *
 * - Autofilling arrays using templates and sub-templates
 * - Conditional processing with basic comparison operators
 * - Basic math function support
 * - Execute arbitrary inline code with special built-in template variables
 * - Custom member functions
 * - Many special tags and built-in operators that aren't defined as part of the API, but are supported in the templates that can be created
 *
 * XTemplate provides the templating mechanism built into {@link Ext.DataView}.
 *
 * The {@link Ext.Template} describes the acceptable parameters to pass to the constructor. The following examples
 * demonstrate all of the supported features.
 *
 * # Sample Data
 *
 * This is the data object used for reference in each code example:
 *
 *     var data = {
 *         name: 'Don Griffin',
 *         title: 'Senior Technomage',
 *         company: 'Sencha Inc.',
 *         drinks: ['Coffee', 'Water', 'More Coffee'],
 *         kids: [
 *             { name: 'Aubrey',  age: 17 },
 *             { name: 'Joshua',  age: 13 },
 *             { name: 'Cale',    age: 10 },
 *             { name: 'Nikol',   age: 5 },
 *             { name: 'Solomon', age: 0 }
 *         ]
 *     };
 *
 * # Auto filling of arrays
 *
 * The **tpl** tag and the **for** operator are used to process the provided data object:
 *
 * - If the value specified in for is an array, it will auto-fill, repeating the template block inside the tpl
 *   tag for each item in the array.
 * - If for="." is specified, the data object provided is examined.
 * - While processing an array, the special variable {#} will provide the current array index + 1 (starts at 1, not 0).
 *
 * Examples:
 *
 *     <tpl for=".">...</tpl>       // loop through array at root node
 *     <tpl for="foo">...</tpl>     // loop through array at foo node
 *     <tpl for="foo.bar">...</tpl> // loop through array at foo.bar node
 *
 * Using the sample data above:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Kids: ',
 *         '<tpl for=".">',       // process the data.kids node
 *             '<p>{#}. {name}</p>',  // use current array index to autonumber
 *         '</tpl></p>'
 *     );
 *     tpl.overwrite(panel.body, data.kids); // pass the kids property of the data object
 *
 * An example illustrating how the **for** property can be leveraged to access specified members of the provided data
 * object to populate the template:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Title: {title}</p>',
 *         '<p>Company: {company}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',     // interrogate the kids property within the data
 *             '<p>{name}</p>',
 *         '</tpl></p>'
 *     );
 *     tpl.overwrite(panel.body, data);  // pass the root node of the data object
 *
 * Flat arrays that contain values (and not objects) can be auto-rendered using the special **`{.}`** variable inside a
 * loop. This variable will represent the value of the array at the current index:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>{name}\'s favorite beverages:</p>',
 *         '<tpl for="drinks">',
 *             '<div> - {.}</div>',
 *         '</tpl>'
 *     );
 *     tpl.overwrite(panel.body, data);
 *
 * When processing a sub-template, for example while looping through a child array, you can access the parent object's
 * members via the **parent** object:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '<tpl if="age &gt; 1">',
 *                 '<p>{name}</p>',
 *                 '<p>Dad: {parent.name}</p>',
 *             '</tpl>',
 *         '</tpl></p>'
 *     );
 *     tpl.overwrite(panel.body, data);
 *
 * # Conditional processing with basic comparison operators
 *
 * The **tpl** tag and the **if** operator are used to provide conditional checks for deciding whether or not to render
 * specific parts of the template.
 *
 * Using the sample data above:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '<tpl if="age &gt; 1">',
 *                 '<p>{name}</p>',
 *             '</tpl>',
 *         '</tpl></p>'
 *     );
 *     tpl.overwrite(panel.body, data);
 *
 * More advanced conditionals are also supported:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '<p>{name} is a ',
 *             '<tpl if="age &gt;= 13">',
 *                 '<p>teenager</p>',
 *             '<tpl elseif="age &gt;= 2">',
 *                 '<p>kid</p>',
 *             '<tpl else>',
 *                 '<p>baby</p>',
 *             '</tpl>',
 *         '</tpl></p>'
 *     );
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '<p>{name} is a ',
 *             '<tpl switch="name">',
 *                 '<tpl case="Aubrey" case="Nikol">',
 *                     '<p>girl</p>',
 *                 '<tpl default">',
 *                     '<p>boy</p>',
 *             '</tpl>',
 *         '</tpl></p>'
 *     );
 *
 * A `break` is implied between each case and default, however, multiple cases can be listed
 * in a single &lt;tpl&gt; tag.
 *
 * # Using double quotes
 *
 * Examples:
 *
 *     var tpl = new Ext.XTemplate(
 *         "<tpl if='age &gt; 1 && age &lt; 10'>Child</tpl>",
 *         "<tpl if='age &gt;= 10 && age &lt; 18'>Teenager</tpl>",
 *         "<tpl if='this.isGirl(name)'>...</tpl>",
 *         '<tpl if="id == \'download\'">...</tpl>',
 *         "<tpl if='needsIcon'><img src='{icon}' class='{iconCls}'/></tpl>",
 *         "<tpl if='name == \"Don\"'>Hello</tpl>"
 *     );
 *
 * # Basic math support
 *
 * The following basic math operators may be applied directly on numeric data values:
 *
 *     + - * /
 *
 * For example:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '<tpl if="age &gt; 1">',  // <-- Note that the > is encoded
 *                 '<p>{#}: {name}</p>',  // <-- Auto-number each item
 *                 '<p>In 5 Years: {age+5}</p>',  // <-- Basic math
 *                 '<p>Dad: {parent.name}</p>',
 *             '</tpl>',
 *         '</tpl></p>'
 *     );
 *     tpl.overwrite(panel.body, data);
 *
 * # Execute arbitrary inline code with special built-in template variables
 *
 * Anything between `{[ ... ]}` is considered code to be executed in the scope of the template.
 * The expression is evaluated and the result is included in the generated result. There are
 * some special variables available in that code:
 *
 * - **out**: The output array into which the template is being appended (using `push` to later
 *   `join`).
 * - **values**: The values in the current scope. If you are using scope changing sub-templates,
 *   you can change what values is.
 * - **parent**: The scope (values) of the ancestor template.
 * - **xindex**: If you are in a looping template, the index of the loop you are in (1-based).
 * - **xcount**: If you are in a looping template, the total length of the array you are looping.
 *
 * This example demonstrates basic row striping using an inline code block and the xindex variable:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Company: {[values.company.toUpperCase() + ", " + values.title]}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '<div class="{[xindex % 2 === 0 ? "even" : "odd"]}">',
 *             '{name}',
 *             '</div>',
 *         '</tpl></p>'
 *      );
 *
 * Any code contained in "verbatim" blocks (using "{% ... %}") will be inserted directly in
 * the generated code for the template. These blocks are not included in the output. This
 * can be used for simple things like break/continue in a loop, or control structures or
 * method calls (when they don't produce output). The `this` references the template instance.
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Company: {[values.company.toUpperCase() + ", " + values.title]}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '{% if (xindex % 2 === 0) continue; %}',
 *             '{name}',
 *             '{% if (xindex > 100) break; %}',
 *             '</div>',
 *         '</tpl></p>'
 *      );
 *
 * # Template member functions
 *
 * One or more member functions can be specified in a configuration object passed into the XTemplate constructor for
 * more complex processing:
 *
 *     var tpl = new Ext.XTemplate(
 *         '<p>Name: {name}</p>',
 *         '<p>Kids: ',
 *         '<tpl for="kids">',
 *             '<tpl if="this.isGirl(name)">',
 *                 '<p>Girl: {name} - {age}</p>',
 *             '<tpl else>',
 *                 '<p>Boy: {name} - {age}</p>',
 *             '</tpl>',
 *             '<tpl if="this.isBaby(age)">',
 *                 '<p>{name} is a baby!</p>',
 *             '</tpl>',
 *         '</tpl></p>',
 *         {
 *             // XTemplate configuration:
 *             disableFormats: true,
 *             // member functions:
 *             isGirl: function(name){
 *                return name == 'Sara Grace';
 *             },
 *             isBaby: function(age){
 *                return age < 1;
 *             }
 *         }
 *     );
 *     tpl.overwrite(panel.body, data);

/**
 * Most of the visual classes you interact with in Sencha Touch are Components. Every Component in Sencha Touch is a
 * subclass of Ext.Component, which means they can all:
 *
 * * Render themselves onto the page using a template
 * * Show and hide themselves at any time
 * * Center themselves on the screen
 * * Enable and disable themselves
 *
 * They can also do a few more advanced things:
 *
 * * Float above other components (windows, message boxes and overlays)
 * * Change size and position on the screen with animation
 * * Dock other Components inside themselves (useful for toolbars)
 * * Align to other components, allow themselves to be dragged around, make their content scrollable & more
 *
 * ## Available Components
 *
 * There are many components available in Sencha Touch, separated into 4 main groups:
 *
 * ### Navigation components
 * * {@link Ext.Toolbar}
 * * {@link Ext.Button}
 * * {@link Ext.TitleBar}
 * * {@link Ext.SegmentedButton}
 * * {@link Ext.Title}
 * * {@link Ext.Spacer}
 *
 * ### Store-bound components
 * * {@link Ext.dataview.DataView}
 * * {@link Ext.Carousel}
 * * {@link Ext.List}
 * * {@link Ext.NestedList}
 *
 * ### Form components
 * * {@link Ext.form.Panel}
 * * {@link Ext.form.FieldSet}
 * * {@link Ext.field.Checkbox}
 * * {@link Ext.field.Hidden}
 * * {@link Ext.field.Slider}
 * * {@link Ext.field.Text}
 * * {@link Ext.picker.Picker}
 * * {@link Ext.picker.Date}
 *
 * ### General components
 * * {@link Ext.Panel}
 * * {@link Ext.tab.Panel}
 * * {@link Ext.Viewport Ext.Viewport}
 * * {@link Ext.Img}
 * * {@link Ext.Map}
 * * {@link Ext.Audio}
 * * {@link Ext.Video}
 * * {@link Ext.Sheet}
 * * {@link Ext.ActionSheet}
 * * {@link Ext.MessageBox}
 *
 *
 * ## Instantiating Components
 *
 * Components are created the same way as all other classes in Sencha Touch - using Ext.create. Here's how we can
 * create a Text field:
 *
 *     var panel = Ext.create('Ext.Panel', {
 *         html: 'This is my panel'
 *     });
 *
 * This will create a {@link Ext.Panel Panel} instance, configured with some basic HTML content. A Panel is just a
 * simple Component that can render HTML and also contain other items. In this case we've created a Panel instance but
 * it won't show up on the screen yet because items are not rendered immediately after being instantiated. This allows
 * us to create some components and move them around before rendering and laying them out, which is a good deal faster
 * than moving them after rendering.
 *
 * To show this panel on the screen now we can simply add it to the global Viewport:
 *
 *     Ext.Viewport.add(panel);
 *
 * Panels are also Containers, which means they can contain other Components, arranged by a layout. Let's revisit the
 * above example now, this time creating a panel with two child Components and a hbox layout:
 *
 *     @example
 *     var panel = Ext.create('Ext.Panel', {
 *         layout: 'hbox',
 *
 *         items: [
 *             {
 *                 xtype: 'panel',
 *                 flex: 1,
 *                 html: 'Left Panel, 1/3rd of total size',
 *                  style: 'background-color: #5E99CC;'
 *             },
 *             {
 *                 xtype: 'panel',
 *                 flex: 2,
 *                 html: 'Right Panel, 2/3rds of total size',
 *                  style: 'background-color: #759E60;'
 *             }
 *         ]
 *     });
 *
 *     Ext.Viewport.add(panel);
 *
 * This time we created 3 Panels - the first one is created just as before but the inner two are declared inline using
 * an xtype. Xtype is a convenient way of creating Components without having to go through the process of using
 * Ext.create and specifying the full class name, instead you can just provide the xtype for the class inside an object
 * and the framework will create the components for you.
 *
 * We also specified a layout for the top level panel - in this case hbox, which splits the horizontal width of the
 * parent panel based on the 'flex' of each child. For example, if the parent Panel above is 300px wide then the first
 * child will be flexed to 100px wide and the second to 200px because the first one was given `flex: 1` and the second
 * `flex: 2`.
 *
 * ## Using xtype
 *
 * xtype is an easy way to create Components without using the full class name. This is especially useful when creating
 * a {@link Ext.Container Container} that contains child Components. An xtype is simply a shorthand way of specifying a
 * Component - for example you can use `xtype: 'panel'` instead of typing out Ext.panel.Panel.
 *
 * Sample usage:
 *
 *     @example miniphone
 *     Ext.create('Ext.Container', {
 *         fullscreen: true,
 *         layout: 'fit',
 *
 *         items: [
 *             {
 *                 xtype: 'panel',
 *                 html: 'This panel is created by xtype'
 *             },
 *             {
 *                 xtype: 'toolbar',
 *                 title: 'So is the toolbar',
 *                 docked: 'top'
 *             }
 *         ]
 *     });
 *
 *
 * ### Common xtypes

 *
 * ## Configuring Components
 *
 * Whenever you create a new Component you can pass in configuration options. All of the configurations for a given
 * Component are listed in the "Config options" section of its class docs page. You can pass in any number of
 * configuration options when you instantiate the Component, and modify any of them at any point later. For example, we
 * can easily modify the {@link Ext.Panel#html html content} of a Panel after creating it:
 *
 *     @example miniphone
 *     // we can configure the HTML when we instantiate the Component
 *     var panel = Ext.create('Ext.Panel', {
 *         fullscreen: true,
 *         html: 'This is a Panel'
 *     });
 *
 *     // we can update the HTML later using the setHtml method:
 *     panel.setHtml('Some new HTML');
 *
 *     // we can retrieve the current HTML using the getHtml method:
 *     Ext.Msg.alert(panel.getHtml()); // displays "Some new HTML"
 *
 * Every config has a getter method and a setter method - these are automatically generated and always follow the same
 * pattern. For example, a config called `html` will receive `getHtml` and `setHtml` methods, a config called `defaultType`
 * will receive `getDefaultType` and `setDefaultType` methods, and so on.
 *
 * ## Further Reading
 *
 * See the [Component & Container Guide](../../../core_concepts/components.html) for more information, and check out the
 * {@link Ext.Container} class docs also.

    /**
     * @cfg {String} xtype
     * The `xtype` configuration option can be used to optimize Component creation and rendering. It serves as a
     * shortcut to the full component name. For example, the component `Ext.button.Button` has an xtype of `button`.
     *
     * You can define your own xtype on a custom {@link Ext.Component component} by specifying the
     * {@link Ext.Class#alias alias} config option with a prefix of `widget`. For example:
     *
     *     Ext.define('PressMeButton', {
     *         extend: 'Ext.button.Button',
     *         alias: 'widget.pressmebutton',
     *         text: 'Press Me'
     *     });
     *
     * Any Component can be created implicitly as an object config with an xtype specified, allowing it to be
     * declared and passed into the rendering pipeline without actually being instantiated as an object. Not only is
     * rendering deferred, but the actual creation of the object itself is also deferred, saving memory and resources
     * until they are actually needed. In complex, nested layouts containing many Components, this can make a
     * noticeable improvement in performance.
     *
     *     // Explicit creation of contained Components:
     *     var panel = new Ext.Panel({
     *        // ...
     *        items: [
     *           Ext.create('Ext.button.Button', {
     *              text: 'OK'
     *           })
     *        ]
     *     });
     *
     *     // Implicit creation using xtype:
     *     var panel = new Ext.Panel({
     *        // ...
     *        items: [{
     *           xtype: 'button',
     *           text: 'OK'
     *        }]
     *     });
     *
     * In the first example, the button will always be created immediately during the panel's initialization. With
     * many added Components, this approach could potentially slow the rendering of the page. In the second example,
     * the button will not be created or rendered until the panel is actually displayed in the browser. If the panel
     * is never displayed (for example, if it is a tab that remains hidden) then the button will never be created and
     * will never consume any resources whatsoever.

/**
 * The HBox (short for horizontal box) layout makes it easy to position items horizontally in a
 * {@link Ext.Container Container}. It can size items based on a fixed width or a fraction of the total width
 * available.
 *
 * For example, an email client might have a list of messages pinned to the left, taking say one third of the available
 * width, and a message viewing panel in the rest of the screen. We can achieve this with hbox layout's *flex* config:
 *
 *     @example
 *     Ext.create('Ext.Container', {
 *         fullscreen: true,
 *         layout: 'hbox',
 *         items: [
 *             {
 *                 html: 'message list',
 *                 style: 'background-color: #5E99CC;',
 *                 flex: 1
 *             },
 *             {
 *                 html: 'message preview',
 *                 style: 'background-color: #759E60;',
 *                 flex: 2
 *             }
 *         ]
 *     });
 *
 * This will give us two boxes - one that's one third of the available width, the other being two thirds of the
 * available width:
 *
 * {@img ../guides/layouts/hbox.jpg}
 *
 * We can also specify fixed widths for child items, or mix fixed widths and flexes. For example, here we have 3 items
 * - one on each side with flex: 1, and one in the center with a fixed width of 100px:
 *
 *     @example
 *     Ext.create('Ext.Container', {
 *         fullscreen: true,
 *         layout: 'hbox',
 *         items: [
 *             {
 *                 html: 'Left item',
 *                 style: 'background-color: #759E60;',
 *                 flex: 1
 *             },
 *             {
 *                 html: 'Center item',
 *                 width: 100
 *             },
 *             {
 *                 html: 'Right item',
 *                 style: 'background-color: #5E99CC;',
 *                 flex: 1
 *             }
 *         ]
 *     });
 *
 * Which gives us an effect like this:
 *
 * {@img ../guides/layouts/hboxfixed.jpg}

/**
 * The VBox (short for vertical box) layout makes it easy to position items horizontally in a
 * {@link Ext.Container Container}. It can size items based on a fixed height or a fraction of the total height
 * available.
 *
 * For example, let's say we want a banner to take one third of the available height, and an information panel in the
 * rest of the screen. We can achieve this with vbox layout's *flex* config:
 *
 *     @example
 *     Ext.create('Ext.Container', {
 *         fullscreen: true,
 *         layout: 'vbox',
 *         items: [
 *             {
 *                 html: 'Awesome banner',
 *                 style: 'background-color: #759E60;',
 *                 flex: 1
 *             },
 *             {
 *                 html: 'Some wonderful information',
 *                 style: 'background-color: #5E99CC;',
 *                 flex: 2
 *             }
 *         ]
 *     });
 *
 * This will give us two boxes - one that's one third of the available height, the other being two thirds of the
 * available height:
 *
 * {@img ../guides/layouts/vbox.jpg}
 *
 * We can also specify fixed heights for child items, or mix fixed heights and flexes. For example, here we have 3
 * items - one at the top and bottom with flex: 1, and one in the center with a fixed width of 100px:
 *
 *     @example preview portrait
 *     Ext.create('Ext.Container', {
 *         fullscreen: true,
 *         layout: 'vbox',
 *         items: [
 *             {
 *                 html: 'Top item',
 *                 style: 'background-color: #5E99CC;',
 *                 flex: 1
 *             },
 *             {
 *                 html: 'Center item',
 *                 height: 100
 *             },
 *             {
 *                 html: 'Bottom item',
 *                 style: 'background-color: #759E60;',
 *                 flex: 1
 *             }
 *         ]
 *     });
 *
 * Which gives us an effect like this:
 *
 * {@img ../guides/layouts/vboxfixed.jpg}

/**
 * Sometimes you want to show several screens worth of information but you've only got a small screen to work with.
 * TabPanels and Carousels both enable you to see one screen of many at a time, and underneath they both use a Card
 * Layout.
 *
 * Card Layout takes the size of the Container it is applied to and sizes the currently active item to fill the
 * Container completely. It then hides the rest of the items, allowing you to change which one is currently visible but
 * only showing one at once:
 *
 * {@img ../guides/layouts/card.jpg}
 *
 *
 * Here the gray box is our Container, and the blue box inside it is the currently active card. The three other cards
 * are hidden from view, but can be swapped in later. While it's not too common to create Card layouts directly, you
 * can do so like this:
 *
 *     var panel = Ext.create('Ext.Panel', {
 *         layout: 'card',
 *         items: [
 *             {
 *                 html: "First Item"
 *             },
 *             {
 *                 html: "Second Item"
 *             },
 *             {
 *                 html: "Third Item"
 *             },
 *             {
 *                 html: "Fourth Item"
 *             }
 *         ]
 *     });
 *
 *     panel.{@link Ext.Container#setActiveItem setActiveItem}(1);
 *
 * Here we create a Panel with a Card Layout and later set the second item active (the active item index is zero-based,
 * so 1 corresponds to the second item). Normally you're better off using a {@link Ext.tab.Panel tab panel} or a
 * {@link Ext.carousel.Carousel carousel}.
 *
 * For a more detailed overview of Sencha Touch 2 layouts, check out the
 * [Layout Guide](../../../core_concepts/layouts.html).

/**
 * Represents a single sorter that can be used as part of the sorters configuration in Ext.mixin.Sortable.
 *
 * A common place for Sorters to be used are {@link Ext.data.Store Stores}. For example:
 *
 *     @example miniphone
 *     var store = Ext.create('Ext.data.Store', {
 *        fields: ['firstName', 'lastName'],
 *        sorters: 'lastName',
 *
 *        data: [
 *            { firstName: 'Tommy',   lastName: 'Maintz' },
 *            { firstName: 'Rob',     lastName: 'Dougan' },
 *            { firstName: 'Ed',      lastName: 'Spencer'},
 *            { firstName: 'Jamie',   lastName: 'Avins'  },
 *            { firstName: 'Nick',    lastName: 'Poulden'}
 *        ]
 *     });
 *
 *     Ext.create('Ext.List', {
 *        fullscreen: true,
 *        itemTpl: '<div class="contact">{firstName} <strong>{lastName}</strong></div>',
 *        store: store
 *     });
 *
 * In the next example, we specify a custom sorter function:
 *
 *     @example miniphone
 *     var store = Ext.create('Ext.data.Store', {
 *         fields: ['person'],
 *         sorters: [
 *             {
 *                 // Sort by first letter of last name, in descending order
 *                 sorterFn: function(record1, record2) {
 *                     var name1 = record1.data.person.name.split('-')[1].substr(0, 1),
 *                         name2 = record2.data.person.name.split('-')[1].substr(0, 1);
 *
 *                     return name1 > name2 ? 1 : (name1 === name2 ? 0 : -1);
 *                 },
 *                 direction: 'DESC'
 *             }

 *         data: [
 *             { person: { name: 'Tommy-Maintz' } },
 *             { person: { name: 'Rob-Dougan'   } },

 * @class Ext.scroll.Scroller
 * @author Jacky Nguyen <jacky@sencha.com>
 *
 * Momentum scrolling is one of the most important part of the framework's UI layer. In Sencha Touch there are
 * several scroller implementations so we can have the best performance on all mobile devices and browsers.
 *
 * Scroller settings can be changed using the {@link Ext.Container#scrollable scrollable} configuration in
 * {@link Ext.Container}. Anything you pass to that method will be passed to the scroller when it is
 * instantiated in your container.
 *
 * Please note that the {@link Ext.Container#getScrollable} method returns an instance of {@link Ext.scroll.View}.
 * So if you need to get access to the scroller after your container has been instantiated, you must use the
 * {@link Ext.scroll.View#getScroller} method.
 *
 *     // lets assume container is a container you have
 *     // created which is scrollable
 *     container.getScrollable().getScroller().setFps(10);
 *
 * ## Example
 *
 * Here is a simple example of how to adjust the scroller settings when using a {@link Ext.Container} (or anything
 * that extends it).
 *
 *      @example
 *      Ext.create('Ext.Container', {
 *           fullscreen: true,
 *           html: "Macaroni cheese roquefort<br>" +
 *                "port-salut. The big cheese<br>" + 
 *                "fondue camembert de normandie<br>" + 
 *                "cow boursin cheese swiss stinking<br>" +  
 *                "bishop. Fromage feta edam fromage<br>" + 
 *                "frais bavarian bergkase paneer<br>" + 
 *                "paneer cheese and wine. Cow danish<br>" +  
 *                "fontina roquefort bocconcini<br>" + 
 *                "jarlsberg parmesan cheesecake<br>" + 
 *                "danish fontina. Mascarpone<br>" +
 *                "bishop. Fromage feta edam fromage<br>" + 
 *                "frais bavarian bergkase paneer<br>" + 
 *                "paneer cheese and wine. Cow danish<br>" +  
 *                "fontina roquefort bocconcini<br>" + 
 *                "jarlsberg parmesan cheesecake<br>" + 
 *                "emmental fromage frais cheesy<br>" + 
 *                "grin say cheese squirty cheese<br>" + 
 *                "parmesan queso. Cheese triangles<br>" + 
 *                "st. agur blue cheese chalk and cheese<br>" + 
 *                "cream cheese lancashire manchego<br>" + 
 *                "taleggio blue castello. Port-salut<br>" + 
 *                "paneer monterey jack<br>" + 
 *                "say cheese fondue.",
 *           scrollable: {
 *              direction: 'vertical'
 *           }
 *       });
 *
 * As you can see, we are passing the {@link #direction} configuration into the scroller instance in our container.
 *
 * You can pass any of the configs below in that {@link Ext.Container#scrollable scrollable} configuration and it will
 * just work.
 *
 * Go ahead and try it in the live code editor above!

/**
 * A Container has all of the abilities of {@link Ext.Component Component}, but lets you nest other Components inside
 * it. Applications are made up of lots of components, usually nested inside one another. Containers allow you to
 * render and arrange child Components inside them. Most apps have a single top-level Container called a Viewport,
 * which takes up the entire screen. Inside of this are child components, for example in a mail app the Viewport
 * Container's two children might be a message List and an email preview pane.
 *
 * Containers give the following extra functionality:
 *
 * - Adding child Components at instantiation and run time
 * - Removing child Components
 * - Specifying a [Layout](../../../core_concepts/layouts.html)
 *
 * Layouts determine how the child Components should be laid out on the screen. In our mail app example we'd use an
 * HBox layout so that we can pin the email list to the left hand edge of the screen and allow the preview pane to
 * occupy the rest. There are several layouts in Sencha Touch 2, each of which help you achieve your desired
 * application structure, further explained in the [Layout guide](../../../core_concepts/layouts.html).
 *
 * ## Adding Components to Containers
 *
 * As we mentioned above, Containers are special Components that can have child Components arranged by a Layout. One of
 * the code samples above showed how to create a Panel with 2 child Panels already defined inside it but it's easy to
 * do this at run time too:
 *
 *     @example miniphone
 *     //this is the Panel we'll be adding below
 *     var aboutPanel = Ext.create('Ext.Panel', {
 *         html: 'About this app'
 *     });
 *
 *     //this is the Panel we'll be adding to
 *     var mainPanel = Ext.create('Ext.Panel', {
 *         fullscreen: true,
 *
 *         layout: 'hbox',
 *         defaults: {
 *             flex: 1
 *         },
 *
 *         items: {
 *             html: 'First Panel',
 *             style: 'background-color: #5E99CC;'
 *         }
 *     });
 *
 *     //now we add the first panel inside the second
 *     mainPanel.add(aboutPanel);
 *
 * Here we created three Panels in total. First we made the aboutPanel, which we might use to tell the user a little
 * about the app. Then we create one called mainPanel, which already contains a third Panel in its
 * {@link Ext.Container#cfg-items items} configuration, with some dummy text ("First Panel"). Finally, we add the first
 * panel to the second by calling the {@link Ext.Container#method-add add} method on `mainPanel`.
 *
 * In this case we gave our mainPanel another hbox layout, but we also introduced some
 * {@link Ext.Container#defaults defaults}. These are applied to every item in the Panel, so in this case every child
 * inside `mainPanel` will be given a `flex: 1` configuration. The effect of this is that when we first render the screen
 * only a single child is present inside `mainPanel`, so that child takes up the full width available to it. Once the
 * `mainPanel.add` line is called though, the `aboutPanel` is rendered inside of it and also given a `flex` of 1, which will
 * cause it and the first panel to both receive half the full width of the `mainPanel`.
 *
 * Likewise, it's easy to remove items from a Container:
 *
 *     mainPanel.remove(aboutPanel);
 *
 * After this line is run everything is back to how it was, with the first child panel once again taking up the full
 * width inside `mainPanel`.
 *
 * ## Further Reading
 *
 * See the [Component & Container Guide](../../../core_concepts/components.html) for more information, and check out the
 * {@link Ext.Container} class docs also.

/**
 * A simple class to display a button in Sencha Touch.
 *
 * There are various different styles of Button you can create by using the {@link #icon},
 * {@link #iconCls}, {@link #iconAlign}, {@link #ui}, and {@link #text}
 * configurations.
 *
 * ## Simple Button
 *
 * Here is a Button in it's simplest form:
 *
 *     @example miniphone
 *     var button = Ext.create('Ext.Button', {
 *         text: 'Button'
 *     });
 *     Ext.Viewport.add({ xtype: 'container', padding: 10, items: [button] });
 *
 * ## Icons
 *
 * You can also create a Button with just an icon using the {@link #iconCls} configuration:
 *
 *     @example miniphone
 *     var button = Ext.create('Ext.Button', {
 *         iconCls: 'refresh'
 *     });
 *     Ext.Viewport.add({ xtype: 'container', padding: 10, items: [button] });
 *
 * Sencha provides the "Font" and "PNG" icons packs from http://wwww.pictos.cc. 
 * Use icons with the {@link Global_CSS#icon icon} mixin in your Sass.
 *
 * ## Badges
 *
 * Buttons can also have a badge on them, by using the {@link #badgeText} configuration:
 *
 *     @example
 *     Ext.create('Ext.Container', {
 *         fullscreen: true,
 *         padding: 10,
 *         items: {
 *             xtype: 'button',
 *             text: 'My Button',
 *             badgeText: '2'
 *         }
 *     });
 *
 * ## UI
 *
 * Buttons also come with a range of different default UIs. Here are the included UIs
 * available (if {@link #$include-button-uis $include-button-uis} is set to `true`):
 *
 * - **normal** - a basic gray button
 * - **back** - a back button
 * - **forward** - a forward button
 * - **round** - a round button
 * - **action** - shaded using the {@link Global_CSS#$active-color $active-color} (dark blue by default)
 * - **decline** - shaded using the {@link Global_CSS#$alert-color $alert-color} (red by default)
 * - **confirm** - shaded using the {@link Global_CSS#$confirm-color $confirm-color} (green by default)
 *
 * You can also append `-round` to each of the last three UI's to give it a round shape:
 *
 * - **action-round**
 * - **decline-round**
 * - **confirm-round**
 *
 * And setting them is very simple:
 *
 *     var uiButton = Ext.create('Ext.Button', {
 *         text: 'My Button',
 *         ui: 'action'
 *     });
 *
 * And how they look:
 *
 *     @example miniphone preview
 *     Ext.create('Ext.Container', {
 *         fullscreen: true,
 *         padding: 4,
 *         defaults: {
 *             xtype: 'button',
 *             margin: 5
 *         },
 *         layout: {
 *             type: 'vbox',
 *             align: 'center'
 *         },
 *         items: [
 *             { ui: 'normal', text: 'normal' },
 *             { ui: 'round', text: 'round' },
 *             { ui: 'action', text: 'action' },
 *             { ui: 'decline', text: 'decline' },
 *             { ui: 'confirm', text: 'confirm' }
 *         ]
 *     });
 *
 * Note that the default {@link #ui} is **normal**.
 *
 * You can also use the {@link #sencha-button-ui sencha-button-ui} CSS Mixin to create your own UIs.
 *
 * ## Example
 *
 * This example shows a bunch of icons on the screen in two toolbars. When you click on the center
 * button, it switches the {@link #iconCls} on every button on the page.
 *
 *     @example preview
 *     Ext.createWidget('container', {
 *         fullscreen: true,
 *         layout: {
 *             type: 'vbox',
 *             pack:'center',
 *             align: 'center'
 *         },
 *         items: [
 *             {
 *                 xtype: 'button',
 *                 text: 'Change iconCls',
 *                 handler: function() {
 *                     // classes for all the icons to loop through.
 *                     var availableIconCls = [
 *                         'action', 'add', 'arrow_down', 'arrow_left',
 *                         'arrow_right', 'arrow_up', 'compose', 'delete',
 *                         'organize', 'refresh', 'reply', 'search',
 *                         'settings', 'star', 'trash', 'maps', 'locate',
 *                         'home'
 *                     ];
 *                     // get the text of this button,
 *                     // so we know which button we don't want to change
 *                     var text = this.getText();
 *
 *                     // use ComponentQuery to find all buttons on the page
 *                     // and loop through all of them
 *                     Ext.Array.forEach(Ext.ComponentQuery.query('button'), function(button) {
 *                         // if the button is the change iconCls button, continue
 *                         if (button.getText() === text) {

/**
 * {@link Ext.ActionSheet ActionSheets} are used to display a list of {@link Ext.Button buttons} in a popup dialog.
 *
 * The key difference between ActionSheet and {@link Ext.Sheet} is that ActionSheets are docked at the bottom of the
 * screen, and the {@link #defaultType} is set to {@link Ext.Button button}.
 *
 * ## Example
 *
 *     @example preview miniphone
 *     var actionSheet = Ext.create('Ext.ActionSheet', {
 *         items: [
 *             {
 *                 text: 'Delete draft',
 *                 ui  : 'decline'
 *             },
 *             {
 *                 text: 'Save draft'
 *             },
 *             {
 *                 text: 'Cancel',
 *                 ui  : 'confirm'
 *             }
 *         ]
 *     });
 *
 *     Ext.Viewport.add(actionSheet);
 *     actionSheet.show();
 *
 * As you can see from the code above, you no longer have to specify a `xtype` when creating buttons within a {@link Ext.ActionSheet ActionSheet},
 * because the {@link #defaultType} is set to {@link Ext.Button button}.
 *

/**
 * The Connection class encapsulates a connection to the page's originating domain, allowing requests to be made either
 * to a configured URL, or to a URL specified at request time.
 *
 * Requests made by this class are asynchronous, and will return immediately. No data from the server will be available
 * to the statement immediately following the {@link #request} call. To process returned data, use a success callback
 * in the request options object, or an {@link #requestcomplete event listener}.
 *
 * # File Uploads
 *
 * File uploads are not performed using normal "Ajax" techniques, that is they are not performed using XMLHttpRequests.
 * Instead the form is submitted in the standard manner with the DOM `<form>` element temporarily modified to have its
 * target set to refer to a dynamically generated, hidden `<iframe>` which is inserted into the document but removed
 * after the return data has been gathered.
 *
 * The server response is parsed by the browser to create the document for the IFRAME. If the server is using JSON to
 * send the return object, then the Content-Type header must be set to "text/html" in order to tell the browser to
 * insert the text unchanged into the document body.
 *
 * Characters which are significant to an HTML parser must be sent as HTML entities, so encode `<` as `&lt;`, `&` as
 * `&amp;` etc.
 *
 * The response text is retrieved from the document, and a fake XMLHttpRequest object is created containing a
 * responseText property in order to conform to the requirements of event handlers and callbacks.
 *
 * Be aware that file upload packets are sent with the content type multipart/form and some server technologies
 * (notably JEE) may require some custom processing in order to retrieve parameter names and parameter values from the
 * packet content.
 *
 * __Note:__ It is not possible to check the response code of the hidden iframe, so the success handler will _always_ fire.

/**
 * {@link Ext.Audio} is a simple class which provides a container for the 
 * [HTML5 Audio element](http://developer.mozilla.org/en-US/docs/Using_HTML5_audio_and_video).
 *
 * ## Recommended File Types/Compression:
 * 
 * * Uncompressed WAV and AIF audio
 * * MP3 audio
 * * AAC-LC
 * * HE-AAC audio
 *
 * ## Notes
 * 
 * On Android devices, the audio tags controls do not show. You must use the {@link #method-play}, 
 * {@link #method-pause}, and {@link #toggle} methods to control the audio (example below).
 *
 * ## Examples
 *
 * This example shows the use of the {@link Ext.Audio} component in a fullscreen container--change 
 * the url: item for the location of an audio file--note that the audio starts on page load:
 *
 *     @example preview
 *     Ext.create('Ext.Container', {
 *         fullscreen: true,
 *         layout: {
 *             type : 'vbox',
 *             pack : 'center',
 *             align: 'stretch'
 *         },
 *         items: [
 *             {
 *                 xtype : 'toolbar',
 *                 docked: 'top',
 *                 title : 'Ext.Audio'
 *             },
 *             {
 *                 xtype: 'audio',
 *                 url  : 'touch-build/examples/audio/crash.mp3'
 *             }
 *         ]
 *     });
 *
 * You can also set the {@link #hidden} configuration of the {@link Ext.Audio} component to true by default,
 * and then control the audio by using the {@link #method-play}, {@link #method-pause}, and {@link #toggle} methods:
 *
 *     @example preview
 *     Ext.create('Ext.Container', {
 *         fullscreen: true,
 *         layout: {
 *             type: 'vbox',
 *             pack: 'center'
 *         },
 *         items: [
 *             {
 *                 xtype : 'toolbar',
 *                 docked: 'top',
 *                 title : 'Ext.Audio'
 *             },
 *             {
 *                 xtype: 'toolbar',
 *                 docked: 'bottom',
 *                 defaults: {
 *                     xtype: 'button',
 *                     handler: function() {
 *                         var container = this.getParent().getParent(),
 *                             // use ComponentQuery to get the audio component (using its xtype)
 *                             audio = container.down('audio');
 *
 *                         audio.toggle();
 *                         this.setText(audio.isPlaying() ? 'Pause' : 'Play');
 *                     }
 *                 },
 *                 items: [
 *                     { text: 'Play', flex: 1 }

/**
 * Provides a cross browser class for retrieving location information.

/**
 * @class Ext.ComponentQuery
 * @extends Object
 * @singleton
 *
 * Provides searching of Components within {@link Ext.ComponentManager} (globally) or a specific
 * {@link Ext.Container} on the document with a similar syntax to a CSS selector.
 *
 * Components can be retrieved by using their {@link Ext.Component xtype} with an optional '.' prefix
 *
 * - `component` or `.component`
 * - `gridpanel` or `.gridpanel`
 *
 * An itemId or id must be prefixed with a #
 *
 * - `#myContainer`
 *
 * Attributes must be wrapped in brackets
 *
 * - `component[autoScroll]`
 * - `panel[title="Test"]`
 *
 * Attributes can use the '=' or '~=' operators to do the pattern matching.
 *
 * The <strong>'='</strong> operator will return the results that <strong>exactly</strong> match:
 *
 *     Ext.Component.query('panel[cls=my-cls]')
 *
 * Will match the following Component:
 *
 *     Ext.create('Ext.Panel', {
 *         cls : 'my-cls'
 *     });
 *
 * The <strong>'~='</strong> operator will return results that <strong>exactly</strong> matches one of the whitespace-separated values:
 *
 *     Ext.Component.query('panel[cls~=my-cls]')
 *
 * Will match the follow Component:
 *
 *     Ext.create('My.Panel', {
 *         cls : 'foo-cls my-cls bar-cls'
 *     });
 *
 * This is because it <strong>exactly</strong> matched the 'my-cls' within the cls config.
 *
 * Member expressions from candidate Components may be tested. If the expression returns a *truthy* value,
 * the candidate Component will be included in the query:
 *
 *     var disabledFields = myFormPanel.query("{isDisabled()}");
 *
 * Pseudo classes may be used to filter results in the same way as in {@link Ext.DomQuery DomQuery}:
 *
 *     // Function receives array and returns a filtered array.
 *     Ext.ComponentQuery.pseudos.invalid = function(items) {
 *         var i = 0, l = items.length, c, result = [];
 *         for (; i < l; i++) {
 *             if (!(c = items[i]).isValid()) {
 *                 result.push(c);
 *             }
 *         }
 *         return result;
 *     };
 *
 *     var invalidFields = myFormPanel.query('field:invalid');
 *     if (invalidFields.length) {
 *         invalidFields[0].getEl().scrollIntoView(myFormPanel.body);
 *         for (var i = 0, l = invalidFields.length; i < l; i++) {
 *             invalidFields[i].getEl().frame("red");
 *         }
 *     }
 *
 * Default pseudos include:
 *
 * - not
 *
 * Queries return an array of components.
 * Here are some example queries.
 *
 *     // retrieve all Ext.Panels in the document by xtype
 *     var panelsArray = Ext.ComponentQuery.query('panel');
 *
 *     // retrieve all Ext.Panels within the container with an id myCt
 *     var panelsWithinmyCt = Ext.ComponentQuery.query('#myCt panel');
 *
 *     // retrieve all direct children which are Ext.Panels within myCt
 *     var directChildPanel = Ext.ComponentQuery.query('#myCt > panel');
 *
 *     // retrieve all grids and trees
 *     var gridsAndTrees = Ext.ComponentQuery.query('gridpanel, treepanel');
 *
 * For easy access to queries based from a particular Container see the {@link Ext.Container#query},
 * {@link Ext.Container#down} and {@link Ext.Container#child} methods. Also see
 * {@link Ext.Component#up}.

/**
 * @class Ext.Decorator
 * @extends Ext.Component
 *
 * In a few words, a Decorator is a Component that wraps around another Component. A typical example of a Decorator is a
 * {@link Ext.field.Field Field}. A form field is nothing more than a decorator around another component, and gives the
 * component a label, as well as extra styling to make it look good in a form.
 *
 * A Decorator can be thought of as a lightweight Container that has only one child item, and no layout overhead.
 * The look and feel of decorators can be styled purely in CSS.
 *
 * Another powerful feature that Decorator provides is config proxying. For example: all config items of a
 * {@link Ext.slider.Slider Slider} also exist in a {@link Ext.field.Slider Slider Field} for API convenience.
 * The {@link Ext.field.Slider Slider Field} simply proxies all corresponding getters and setters
 * to the actual {@link Ext.slider.Slider Slider} instance. Writing out all the setters and getters to do that is a tedious task
 * and a waste of code space. Instead, when you sub-class Ext.Decorator, all you need to do is to specify those config items
 * that you want to proxy to the Component using a special 'proxyConfig' class property. Here's how it may look like
 * in a Slider Field class:
 *
 *     Ext.define('My.field.Slider', {
 *         extend: 'Ext.Decorator',
 *
 *         config: {
 *             component: {
 *                 xtype: 'slider'
 *             }
 *         },
 *
 *         proxyConfig: {
 *             minValue: 0,
 *             maxValue: 100,
 *             increment: 1
 *         }
 *
 *         // ...
 *     });

/**
 * This is a simple way to add an image of any size to your application and have it participate in the layout system
 * like any other component. This component typically takes between 1 and 3 configurations - a {@link #src}, and
 * optionally a {@link #height} and a {@link #width}:
 *
 *     @example miniphone
 *     var img = Ext.create('Ext.Img', {
 *         src: 'http://www.sencha.com/assets/images/sencha-avatar-64x64.png',
 *         height: 64,
 *         width: 64
 *     });
 *     Ext.Viewport.add(img);
 *
 * It's also easy to add an image into a panel or other container using its xtype:
 *
 *     @example miniphone
 *     Ext.create('Ext.Panel', {
 *         fullscreen: true,
 *         layout: 'hbox',
 *         items: [
 *             {
 *                 xtype: 'image',
 *                 src: 'http://www.sencha.com/assets/images/sencha-avatar-64x64.png',
 *                 flex: 1
 *             },
 *             {
 *                 xtype: 'panel',
 *                 flex: 2,
 *                 html: 'Sencha Inc.<br/>1700 Seaport Boulevard Suite 120, Redwood City, CA'
 *             }
 *         ]
 *     });
 *
 * Here we created a panel which contains an image (a profile picture in this case) and a text area to allow the user
 * to enter profile information about themselves. In this case we used an {@link Ext.layout.HBox hbox layout} and
 * flexed the image to take up one third of the width and the text area to take two thirds of the width. See the
 * {@link Ext.layout.HBox hbox docs} for more information on flexing items.

The {@link Ext.Spacer} component is generally used to put space between items in {@link Ext.Toolbar} components.

## Examples

By default the {@link #flex} configuration is set to 1:

    @example miniphone preview
    Ext.create('Ext.Container', {
        fullscreen: true,
        items: [
            {
                xtype : 'toolbar',
                docked: 'top',
                items: [
                    {
                        xtype: 'button',
                        text : 'Button One'
                    },
                    {
                        xtype: 'spacer'
                    },
                    {
                        xtype: 'button',
                        text : 'Button Two'
                    }
                ]
            }
        ]
    });

Alternatively you can just set the {@link #width} configuration which will get the {@link Ext.Spacer} a fixed width:

    @example preview
    Ext.create('Ext.Container', {
        fullscreen: true,
        layout: {
            type: 'vbox',
            pack: 'center',
            align: 'stretch'
        },
        items: [
            {
                xtype : 'toolbar',
                docked: 'top',
                items: [
                    {
                        xtype: 'button',
                        text : 'Button One'
                    },
                    {
                        xtype: 'spacer',
                        width: 50
                    },
                    {
                        xtype: 'button',
                        text : 'Button Two'
                    }
                ]
            },
            {
                xtype: 'container',
                items: [
                    {
                        xtype: 'button',
                        text : 'Change Ext.Spacer width',
                        handler: function() {
                            //get the spacer using ComponentQuery
                            var spacer = Ext.ComponentQuery.query('spacer')[0],
                                from = 10,
                                to = 250;

                            //set the width to a random number
                            spacer.setWidth(Math.floor(Math.random() * (to - from + 1) + from));
                        }
                    }
                ]
            }
        ]
    });

You can also insert multiple {@link Ext.Spacer}'s:

    @example preview
    Ext.create('Ext.Container', {
        fullscreen: true,
        items: [
            {

                        text : 'Button One'
                    },
                    {
                        xtype: 'spacer'
                    },
                    {
                        xtype: 'button',
                        text : 'Button Two'
                    },
                    {
                        xtype: 'spacer',
                        width: 20
                    },
                    {
                        xtype: 'button',

                ]
            }

/**
 * {@link Ext.Toolbar}s are most commonly used as docked items as within a {@link Ext.Container}. They can be docked either `top` or `bottom` using the {@link #docked} configuration.

 * ## Notes
 *
 * You must use a HTML5 doctype for {@link #docked} `bottom` to work. To do this, simply add the following code to the HTML file:
 *
 *     <!doctype html>
 *
 * So your index.html file should look a little like this:
 *
 *     <!doctype html>
 *     <html>
 *         <head>
 *             <title>MY application title</title>
 *             ...
 *

/**
 * Field is the base class for all form fields used in Sencha Touch. It provides a lot of shared functionality to all
 * field subclasses (for example labels, simple validation, {@link #clearIcon clearing} and tab index management), but
 * is rarely used directly. Instead, it is much more common to use one of the field subclasses:
 *
 *     xtype            Class
 *     ---------------------------------------
 *     textfield        {@link Ext.field.Text}
 *     numberfield      {@link Ext.field.Number}
 *     textareafield    {@link Ext.field.TextArea}
 *     hiddenfield      {@link Ext.field.Hidden}
 *     radiofield       {@link Ext.field.Radio}
 *     filefield        {@link Ext.field.File}
 *     checkboxfield    {@link Ext.field.Checkbox}
 *     selectfield      {@link Ext.field.Select}
 *     togglefield      {@link Ext.field.Toggle}
 *     fieldset         {@link Ext.form.FieldSet}
 *
 * Fields are normally used within the context of a form and/or fieldset. See the {@link Ext.form.Panel FormPanel}
 * and {@link Ext.form.FieldSet FieldSet} docs for examples on how to put those together, or the list of links above
 * for usage of individual field types. If you wish to create your own Field subclasses you can extend this class,
 * though it is sometimes more useful to extend {@link Ext.field.Text} as this provides additional text entry
 * functionality.

 *                         xtype: 'textfield',
 *                         label: 'Last Name',
 *                         name: 'lastName'
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * This creates two text fields inside a form. Text Fields can also be created outside of a Form, like this:
 *
 *     Ext.create('Ext.field.Text', {
 *         label: 'Your Name',
 *         value: 'Ed Spencer'
 *     });
 *
 * ## Configuring
 *
 * Text field offers several configuration options, including {@link #placeHolder}, {@link #maxLength},
 * {@link #autoComplete}, {@link #autoCapitalize} and {@link #autoCorrect}. For example, here is how we would configure
 * a text field to have a maximum length of 10 characters, with placeholder text that disappears when the field is
 * focused:
 *
 *     Ext.create('Ext.field.Text', {
 *         label: 'Username',
 *         maxLength: 10,
 *         placeHolder: 'Enter your username'
 *     });
 *
 * The autoComplete, autoCapitalize and autoCorrect configs simply set those attributes on the text field and allow the
 * native browser to provide those capabilities. For example, to enable auto complete and auto correct, simply
 * configure your text field like this:
 *
 *     Ext.create('Ext.field.Text', {
 *         label: 'Username',
 *         autoComplete: true,
 *         autoCorrect: true
 *     });
 *
 * These configurations will be picked up by the native browser, which will enable the options at the OS level.
 *
 * Text field inherits from {@link Ext.field.Field}, which is the base class for all fields in Sencha Touch and provides
 * a lot of shared functionality for all fields, including setting values, clearing and basic validation. See the
 * {@link Ext.field.Field} documentation to see how to leverage its capabilities.

 * showing a MessageBox will not cause the code to stop. For this reason, if you have code that should only run _after_
 * some user feedback from the MessageBox, you must use a callback function (see the `fn` configuration option parameter
 * for the {@link #method-show show} method for more details).
 *
 *     @example preview
 *     Ext.Msg.alert('Title', 'The quick brown fox jumped over the lazy dog.', Ext.emptyFn);
 *
 * Checkout {@link Ext.Msg} for more examples.

         *     @example preview
         *     Ext.Msg.prompt('Name', 'Please enter your name:', function(text) {

         *     });
         *
         * ### Confirm
         * Use the {@link #confirm} method to show a confirmation alert (shows yes and no buttons).
         *
         *     @example preview
         *     Ext.Msg.confirm("Confirmation", "Are you sure you want to do that?", Ext.emptyFn);

/**
 * A 'Toast' is a simple modal message that is displayed on the screen and then automatically closed by a timeout or by a user tapping
 * outside of the toast itself. Think about it like a text only alert box that will self destruct. **A Toast should not be instantiated manually**
 * but creating by calling 'Ext.toast(message, timeout)'. This will create one reusable toast container and content will be swapped out as
 * toast messages are queued or displayed.
 *
 *  # Simple Toast
 *
 *      @example miniphone
 *      Ext.toast('Hello Sencha!'); // Toast will close in 1000 milliseconds (default)
 *
 *  # Toast with Timeout
 *
 *      @example miniphone
 *      Ext.toast('Hello Sencha!', 5000); // Toast will close in 5000 milliseconds
 *
 *  # Toast with config
 *
 *      @example miniphone
 *      Ext.toast({message: 'Hello Sencha!', timeout: 2000}); // Toast will close in 2000 milliseconds
 *
 * # Multiple Toasts queued
 *
 *      @example miniphone
 *      Ext.toast('Hello Sencha!');
 *      Ext.toast('Hello Sencha Again!');
 *      Ext.toast('Hello Sencha One More Time!');

 *
 * ## Notes
 *
 * - There are quite a few issues with the `<video>` tag on Android devices. On Android 2+, the video will
 * appear and play on first attempt, but any attempt afterwards will not work.
 *
 * ## Useful Properties
 *
 * - {@link #url}
 * - {@link #autoPause}
 * - {@link #autoResume}
 *
 * ## Useful Methods
 *
 * - {@link #method-pause}
 * - {@link #method-play}
 * - {@link #toggle}
 *
 * ## Example
 *
 *     var panel = Ext.create('Ext.Panel', {

/**
 * @author Ed Spencer
 *
 * Controllers are responsible for responding to events that occur within your app. If your app contains a Logout
 * {@link Ext.Button button} that your user can tap on, a Controller would listen to the Button's tap event and take
 * the appropriate action. It allows the View classes to handle the display of data and the Model classes to handle the
 * loading and saving of data - the Controller is the glue that binds them together.
 *
 * ## Relation to Ext.app.Application
 *
 * Controllers exist within the context of an {@link Ext.app.Application Application}. An Application usually consists
 * of a number of Controllers, each of which handle a specific part of the app. For example, an Application that
 * handles the orders for an online shopping site might have controllers for Orders, Customers and Products.
 *
 * All of the Controllers that an Application uses are specified in the Application's
 * {@link Ext.app.Application#controllers} config. The Application automatically instantiates each Controller and keeps
 * references to each, so it is unusual to need to instantiate Controllers directly. By convention each Controller is
 * named after the thing (usually the Model) that it deals with primarily, usually in the plural - for example if your
 * app is called 'MyApp' and you have a Controller that manages Products, convention is to create a
 * MyApp.controller.Products class in the file app/controller/Products.js.
 *
 * ## Refs and Control
 *
 * The centerpiece of Controllers is the twin configurations {@link #refs} and {@link #cfg-control}. These are used to
 * easily gain references to Components inside your app and to take action on them based on events that they fire.
 * Let's look at {@link #refs} first:
 *
 * ### Refs
 *
 * Refs leverage the powerful {@link Ext.ComponentQuery ComponentQuery} syntax to easily locate Components on your
 * page. We can define as many refs as we like for each Controller, for example here we define a ref called 'nav' that
 * finds a Component on the page with the ID 'mainNav'. We then use that ref in the addLogoutButton beneath it:
 *
 *     Ext.define('MyApp.controller.Main', {
 *         extend: 'Ext.app.Controller',
 *
 *         config: {
 *             refs: {
 *                 nav: '#mainNav'
 *             }
 *         },
 *
 *         addLogoutButton: function() {
 *             this.getNav().add({
 *                 text: 'Logout'
 *             });
 *         }
 *     });
 *
 * Usually, a ref is just a key/value pair - the key ('nav' in this case) is the name of the reference that will be
 * generated, the value ('#mainNav' in this case) is the {@link Ext.ComponentQuery ComponentQuery} selector that will
 * be used to find the Component.
 *
 * Underneath that, we have created a simple function called addLogoutButton which uses this ref via its generated
 * 'getNav' function. These getter functions are generated based on the refs you define and always follow the same
 * format - 'get' followed by the capitalized ref name. In this case we're treating the nav reference as though it's a
 * {@link Ext.Toolbar Toolbar}, and adding a Logout button to it when our function is called. This ref would recognize
 * a Toolbar like this:
 *
 *     Ext.create('Ext.Toolbar', {
 *         id: 'mainNav',
 *
 *         items: [
 *             {
 *                 text: 'Some Button'
 *             }
 *         ]
 *     });
 *
 * Assuming this Toolbar has already been created by the time we run our 'addLogoutButton' function (we'll see how that
 * is invoked later), it will get the second button added to it.
 *
 * ### Advanced Refs
 *
 * Refs can also be passed a couple of additional options, beyond name and selector. These are autoCreate and xtype,
 * which are almost always used together:
 *
 *     Ext.define('MyApp.controller.Main', {
 *         extend: 'Ext.app.Controller',
 *
 *         config: {
 *             refs: {
 *                 nav: '#mainNav',
 *
 *                 infoPanel: {
 *                     selector: 'tabpanel panel[name=fish] infopanel',
 *                     xtype: 'infopanel',
 *                     autoCreate: true
 *                 }
 *             }
 *         }
 *     });
 *
 * We've added a second ref to our Controller. Again the name is the key, 'infoPanel' in this case, but this time we've
 * passed an object as the value instead. This time we've used a slightly more complex selector query - in this example
 * imagine that your app contains a {@link Ext.tab.Panel tab panel} and that one of the items in the tab panel has been
 * given the name 'fish'. Our selector matches any Component with the xtype 'infopanel' inside that tab panel item.
 *
 * The difference here is that if that infopanel does not exist already inside the 'fish' panel, it will be
 * automatically created when you call this.getInfoPanel inside your Controller. The Controller is able to do this
 * because we provided the xtype to instantiate with in the event that the selector did not return anything.
 *
 * ### Control
 *
 * The sister config to {@link #refs} is {@link #cfg-control}. {@link #cfg-control Control} is the means by which your listen
 * to events fired by Components and have your Controller react in some way. Control accepts both ComponentQuery
 * selectors and refs as its keys, and listener objects as values - for example:
 *
 *     Ext.define('MyApp.controller.Main', {
 *         extend: 'Ext.app.Controller',
 *
 *         config: {
 *             control: {
 *                 loginButton: {
 *                     tap: 'doLogin'
 *                 },
 *                 'button[action=logout]': {
 *                     tap: 'doLogout'
 *                 }
 *             },
 *
 *             refs: {
 *                 loginButton: 'button[action=login]'
 *             }
 *         },
 *
 *         doLogin: function() {
 *             //called whenever the Login button is tapped
 *         },
 *
 *         doLogout: function() {
 *             //called whenever any Button with action=logout is tapped
 *         }
 *     });
 *
 * Here we have set up two control declarations - one for our loginButton ref and the other for any Button on the page
 * that has been given the action 'logout'. For each declaration we passed in a single event handler - in each case
 * listening for the 'tap' event, specifying the action that should be called when that Button fires the tap event.
 * Note that we specified the 'doLogin' and 'doLogout' methods as strings inside the control block - this is important.
 *
 * You can listen to as many events as you like in each control declaration, and mix and match ComponentQuery selectors
 * and refs as the keys.
 *
 * ## Routes
 *
 * As of Sencha Touch 2, Controllers can now directly specify which routes they are interested in. This enables us to
 * provide history support within our app, as well as the ability to deeply link to any part of the application that we
 * provide a route for.
 *
 * For example, let's say we have a Controller responsible for logging in and viewing user profiles, and want to make
 * those screens accessible via urls. We could achieve that like this:
 *
 *     Ext.define('MyApp.controller.Users', {
 *         extend: 'Ext.app.Controller',
 *
 *         config: {
 *             routes: {
 *                 'login': 'showLogin',
 *                 'user/:id': 'showUserById'
 *             },
 *
 *             refs: {
 *                 main: '#mainTabPanel'
 *             }
 *         },
 *
 *         //uses our 'main' ref above to add a loginpanel to our main TabPanel (note that
 *         //'loginpanel' is a custom xtype created for this application)
 *         showLogin: function() {
 *             this.getMain().add({
 *                 xtype: 'loginpanel'
 *             });
 *         },
 *
 *         //Loads the User then adds a 'userprofile' view to the main TabPanel
 *         showUserById: function(id) {
 *             MyApp.model.User.load(id, {
 *                 scope: this,
 *                 success: function(user) {
 *                     this.getMain().add({
 *                         xtype: 'userprofile',
 *                         user: user
 *                     });
 *                 }
 *             });
 *         }
 *     });
 *
 * The routes we specified above simply map the contents of the browser address bar to a Controller function to call
 * when that route is matched. The routes can be simple text like the login route, which matches against
 * http://myapp.com/#login, or contain wildcards like the 'user/:id' route, which matches urls like
 * http://myapp.com/#user/123. Whenever the address changes the Controller automatically calls the function specified.
 *
 * Note that in the showUserById function we had to first load the User instance. Whenever you use a route, the
 * function that is called by that route is completely responsible for loading its data and restoring state. This is
 * because your user could either send that url to another person or simply refresh the page, which we wipe clear any
 * cached data you had already loaded. There is a more thorough discussion of restoring state with routes in the
 * [application architecture guides](../../../core_concepts/about_applications.html).
 *
 * ## Advanced Usage
 *
 * See [the Controllers guide](../../../core_concepts/controllers.html) for advanced Controller 
 * usage including before filters and customizing for different devices.

/**
 * @author Ed Spencer
 *
 * A Profile represents a range of devices that fall under a common category. For the vast majority of apps that use
 * device profiles, the app defines a Phone profile and a Tablet profile. Doing this enables you to easily customize
 * the experience for the different sized screens offered by those device types.
 *
 * Only one Profile can be active at a time, and each Profile defines a simple {@link #isActive} function that should
 * return either true or false. The first Profile to return true from its isActive function is set as your Application's
 * {@link Ext.app.Application#currentProfile current profile}.
 *
 * A Profile can define any number of {@link #models}, {@link #views}, {@link #controllers} and {@link #stores} which
 * will be loaded if the Profile is activated. It can also define a {@link #launch} function that will be called after
 * all of its dependencies have been loaded, just before the {@link Ext.app.Application#launch application launch}
 * function is called.
 *
 * ## Sample Usage
 *
 * First you need to tell your Application about your Profile(s):
 *
 *     Ext.application({
 *         name: 'MyApp',
 *         profiles: ['Phone', 'Tablet']
 *     });
 *
 * This will load app/profile/Phone.js and app/profile/Tablet.js. Here's how we might define the Phone profile:
 *
 *     Ext.define('MyApp.profile.Phone', {
 *         extend: 'Ext.app.Profile',
 *
 *         views: ['Main'],
 *
 *         isActive: function() {
 *             return Ext.os.is('Phone');
 *         }
 *     });
 *
 * The isActive function returns true if we detect that we are running on a phone device. If that is the case the
 * Application will set this Profile active and load the 'Main' view specified in the Profile's {@link #views} config.
 *
 * ## Class Specializations
 *
 * Because Profiles are specializations of an application, all of the models, views, controllers and stores defined
 * in a Profile are expected to be namespaced under the name of the Profile. Here's an expanded form of the example
 * above:
 *
 *     Ext.define('MyApp.profile.Phone', {
 *         extend: 'Ext.app.Profile',
 *
 *         views: ['Main'],
 *         controllers: ['Signup'],
 *         models: ['MyApp.model.Group'],
 *
 *         isActive: function() {
 *             return Ext.os.is('Phone');
 *         }
 *     });
 *
 * In this case, the Profile is going to load *app/view/phone/Main.js*, *app/controller/phone/Signup.js* and
 * *app/model/Group.js*. Notice that in each of the first two cases the name of the profile ('phone' in this case) was
 * injected into the class names. In the third case we specified the full Model name (for Group) so the Profile name
 * was not injected.
 *
 * For a fuller understanding of the ideas behind Profiles and how best to use them in your app, we suggest you read
 * the [device profiles guide](../../../core_concepts/device_profiles.html).

 *
 * Ext.app.Application defines the set of {@link Ext.data.Model Models}, {@link Ext.app.Controller Controllers},
 * {@link Ext.app.Profile Profiles}, {@link Ext.data.Store Stores} and {@link Ext.Component Views} that an application
 * consists of. It automatically loads all of those dependencies and can optionally specify a {@link #launch} function
 * that will be called when everything is ready.
 *
 * Sample usage:
 *
 *     Ext.application({
 *         name: 'MyApp',
 *
 *         models: ['User', 'Group'],
 *         stores: ['Users'],
 *         controllers: ['Users'],
 *         views: ['Main', 'ShowUser'],
 *
 *         launch: function() {
 *             Ext.create('MyApp.view.Main');
 *         }
 *     });
 *
 * Creating an Application instance is the only time in Sencha Touch that we don't use Ext.create to create the new
 * instance. Instead, the {@link Ext#application} function instantiates an Ext.app.Application internally,
 * automatically loading the Ext.app.Application class if it is not present on the page already and hooking in to
 * {@link Ext#onReady} before creating the instance itself. An alternative is to use Ext.create inside an Ext.onReady
 * callback, but Ext.application is preferred.
 *
 * ## Dependencies
 *
 * Application follows a simple convention when it comes to specifying the controllers, views, models, stores and
 * profiles it requires. By default it expects each of them to be found inside the *app/controller*, *app/view*,
 * *app/model*, *app/store* and *app/profile* directories in your app - if you follow this convention you can just
 * specify the last part of each class name and Application will figure out the rest for you:
 *
 *     Ext.application({
 *         name: 'MyApp',
 *
 *         controllers: ['Users'],
 *         models: ['User', 'Group'],
 *         stores: ['Users'],
 *         views: ['Main', 'ShowUser']
 *     });
 *
 * The example above will load 6 files:
 *
 * - app/model/User.js
 * - app/model/Group.js
 * - app/store/Users.js
 * - app/controller/Users.js
 * - app/view/Main.js
 * - app/view/ShowUser.js
 *
 * ### Nested Dependencies
 *
 * For larger apps it's common to split the models, views and controllers into subfolders to keep the project
 * organized. This is especially true of views - it's not unheard of for large apps to have over a hundred separate
 * view classes so organizing them into folders can make maintenance much simpler.
 *
 * To specify dependencies in subfolders just use a period (".") to specify the folder:
 *
 *     Ext.application({
 *         name: 'MyApp',
 *
 *         controllers: ['Users', 'nested.MyController'],
 *         views: ['products.Show', 'products.Edit', 'user.Login']
 *     });
 *
 * In this case these 5 files will be loaded:
 *
 * - app/controller/Users.js
 * - app/controller/nested/MyController.js
 * - app/view/products/Show.js
 * - app/view/products/Edit.js
 * - app/view/user/Login.js
 *
 * Note that we can mix and match within each configuration here - for each model, view, controller, profile or store
 * you can specify either just the final part of the class name (if you follow the directory conventions), or the full
 * class name.
 *
 * ### External Dependencies
 *
 * Finally, we can specify application dependencies from outside our application by fully-qualifying the classes we
 * want to load. A common use case for this is sharing authentication logic between multiple applications. Perhaps you
 * have several apps that login via a common user database and you want to share that code between them. An easy way to
 * do this is to create a folder alongside your app folder and then add its contents as dependencies for your app.
 *
 * For example, let's say our shared login code contains a login controller, a user model and a login form view. We
 * want to use all of these in our application:
 *
 *     Ext.Loader.setPath({
 *         'Auth': 'Auth'
 *     });
 *
 *     Ext.application({
 *         views: ['Auth.view.LoginForm', 'Welcome'],
 *         controllers: ['Auth.controller.Sessions', 'Main'],
 *         models: ['Auth.model.User']
 *     });
 *
 * This will load the following files:
 *
 * - Auth/view/LoginForm.js
 * - Auth/controller/Sessions.js
 * - Auth/model/User.js
 * - app/view/Welcome.js
 * - app/controller/Main.js
 *
 * The first three were loaded from outside our application, the last two from the application itself. Note how we can
 * still mix and match application files and external dependency files.
 *
 * Note that to enable the loading of external dependencies we just have to tell the Loader where to find those files,
 * which is what we do with the Ext.Loader.setPath call above. In this case we're telling the Loader to find any class
 * starting with the 'Auth' namespace inside our 'Auth' folder. This means we can drop our common Auth code into our
 * application alongside the app folder and the framework will be able to figure out how to load everything.
 *
 * ## Launching
 *
 * Each Application can define a {@link Ext.app.Application#launch launch} function, which is called as soon as all of
 * your app's classes have been loaded and the app is ready to be launched. This is usually the best place to put any
 * application startup logic, typically creating the main view structure for your app.
 *
 * In addition to the Application launch function, there are two other places you can put app startup logic. Firstly,
 * each Controller is able to define an {@link Ext.app.Controller#init init} function, which is called before the
 * Application launch function. Secondly, if you are using Device Profiles, each Profile can define a
 * {@link Ext.app.Profile#launch launch} function, which is called after the Controller init functions but before the
 * Application launch function.
 *
 * Note that only the active Profile has its launch function called - for example if you define profiles for Phone and
 * Tablet and then launch the app on a tablet, only the Tablet Profile's launch function is called.
 *
 * 1. Controller#init functions called
 * 2. Profile#launch function called
 * 3. Application#launch function called
 * 4. Controller#launch functions called
 *
 * When using Profiles it is common to place most of the bootup logic inside the Profile launch function because each
 * Profile has a different set of views that need to be constructed at startup.
 *
 * ## Adding to Home Screen
 *
 * iOS devices allow your users to add your app to their home screen for easy access. iOS allows you to customize
 * several aspects of this, including the icon that will appear on the home screen and the startup image. These can be
 * specified in the Ext.application setup block:
 *
 *     Ext.application({
 *         name: 'MyApp',
 *
 *         {@link #icon}: 'resources/img/icon.png',
 *         {@link #isIconPrecomposed}: false,
 *         {@link #startupImage}: {
 *             '320x460': 'resources/startup/320x460.jpg',
 *             '640x920': 'resources/startup/640x920.png',
 *             '640x1096': 'resources/startup/640x1096.png',
 *             '768x1004': 'resources/startup/768x1004.png',
 *             '748x1024': 'resources/startup/748x1024.png',
 *             '1536x2008': 'resources/startup/1536x2008.png',
 *             '1496x2048': 'resources/startup/1496x2048.png'
 *         }
 *     });
 *
 * When the user adds your app to the home screen, your resources/img/icon.png file will be used as the application
 * {@link #icon}. We also used the {@link #isIconPrecomposed} configuration to turn off the gloss effect that is automatically added
 * to icons in iOS. Finally we used the {@link #startupImage} configuration to provide the images that will be displayed 
 * while your application is starting up. See also {@link #statusBarStyle}.

 *
 * Carousels, like [tabs](../../../components/tabpanel.html), are a great way to allow the user to swipe through multiple full-screen pages.
 * A Carousel shows only one of its pages at a time but allows you to swipe through with your finger.
 *
 * Carousels can be oriented either horizontally or vertically and are easy to configure - they just work like any other
 * Container. Here's how to set up a simple horizontal Carousel:
 *
 *     @example
 *     Ext.create('Ext.Carousel', {
 *         fullscreen: true,
 *
 *         defaults: {
 *             styleHtmlContent: true
 *         },
 *
 *         items: [
 *             {
 *                 html : 'Item 1',
 *                 style: 'background-color: #5E99CC'
 *             },
 *             {
 *                 html : 'Item 2',
 *                 style: 'background-color: #759E60'
 *             },
 *             {
 *                 html : 'Item 3'
 *             }
 *         ]
 *     });
 *
 * We can also make Carousels orient themselves vertically:
 *
 *     @example preview
 *     Ext.create('Ext.Carousel', {
 *         fullscreen: true,
 *         direction: 'vertical',
 *
 *         defaults: {
 *             styleHtmlContent: true
 *         },
 *
 *         items: [
 *             {
 *                 html : 'Item 1',
 *                 style: 'background-color: #759E60'
 *             },
 *             {
 *                 html : 'Item 2',
 *                 style: 'background-color: #5E99CC'
 *             }
 *         ]
 *     });
 *
 * ### Common Configurations
 * * {@link #ui} defines the style of the carousel
 * * {@link #direction} defines the direction of the carousel
 * * {@link #indicator} defines if the indicator show be shown
 *
 * ### Useful Methods
 * * {@link #next} moves to the next card
 * * {@link #previous} moves to the previous card
 * * {@link #setActiveItem} moves to the passed card
 *
 * ## Further Reading
 *
 * For more information about Carousels see the [Carousel guide](../../../components/carousel.html).

/**
 * @author Ed Spencer
 *
 * Readers are used to interpret data to be loaded into a {@link Ext.data.Model Model} instance or a {@link
 * Ext.data.Store Store} - often in response to an AJAX request. In general there is usually no need to create
 * a Reader instance directly, since a Reader is almost always used together with a {@link Ext.data.proxy.Proxy Proxy},
 * and is configured using the Proxy's {@link Ext.data.proxy.Proxy#cfg-reader reader} configuration property:
 *
 *     Ext.define("User", {
 *         extend: "Ext.data.Model",
 *         config: {
 *             fields: [
 *                 "id",
 *                 "name"
 *             ]
 *         }
 *     });
 *
 *     Ext.create("Ext.data.Store", {
 *         model: "User",
 *         autoLoad: true,
 *         storeId: "usersStore",
 *         proxy: {
 *             type: "ajax",
 *             url : "users.json",
 *             reader: {
 *                 type: "json",
 *                 rootProperty: "users"
 *             }
 *         }
 *     });
 *
 *     Ext.create("Ext.List", {
 *         fullscreen: true,
 *         itemTpl: "{name} (id: '{id}')",
 *         store: "usersStore"
 *     });
 *
 * The above reader is configured to consume a JSON string that looks something like this:
 *
 *     {
 *         "success": true,
 *         "users": [
 *             { "name": "User 1" },
 *             { "name": "User 2" }
 *         ]
 *     }
 *
 *
 * # Loading Nested Data
 *
 * Readers have the ability to automatically load deeply-nested data objects based on the {@link Ext.data.association.Association
 * associations} configured on each Model. Below is an example demonstrating the flexibility of these associations in a
 * fictional CRM system which manages a User, their Orders, OrderItems and Products. First we'll define the models:
 *
 *     Ext.define("User", {
 *         extend: "Ext.data.Model",
 *         config: {
 *             fields: [
 *                 "id",
 *                 "name"
 *             ],
 *             hasMany: {
 *                 model: "Order",
 *                 name: "orders"
 *             },
 *             proxy: {
 *                 type: "rest",
 *                 url : "users.json",
 *                 reader: {
 *                     type: "json",
 *                     rootProperty: "users"
 *                 }
 *             }
 *         }
 *     });
 *
 *     Ext.define("Order", {
 *         extend: "Ext.data.Model",
 *         config: {
 *             fields: [
 *                 "id", "total"
 *             ],
 *             hasMany: {
 *                 model: "OrderItem",
 *                 name: "orderItems",
 *                 associationKey: "order_items"
 *             },
 *             belongsTo: "User"
 *         }
 *     });
 *
 *     Ext.define("OrderItem", {
 *         extend: "Ext.data.Model",
 *         config: {
 *             fields: [

 *                 "quantity",
 *                 "order_id",
 *                 "product_id"
 *             ],
 *             belongsTo: [
 *                 "Order", {
 *                     model: "Product",
 *                     associationKey: "product"
 *                 }
 *             ]
 *         }
 *     });
 *

 *         config: {
 *             fields: [
 *                 "id",
 *                 "name"
 *             ]
 *         },
 *         hasMany: "OrderItem"
 *     });
 *
 *     var store = Ext.create('Ext.data.Store', {
 *         model: "User"
 *     });
 *
 *     store.load({
 *         callback: function() {
 *             var output = [];
 *
 *             // the user that was loaded
 *             var user = store.first();
 *
 *             output.push("Orders for " + user.get('name') + ":");
 *
 *             // iterate over the Orders for each User
 *             user.orders().each(function(order) {
 *                 output.push("Order ID: " + order.get('id') + ", which contains items:");
 *
 *                 // iterate over the OrderItems for each Order
 *                 order.orderItems().each(function(orderItem) {
 *                     // We know that the Product data is already loaded, so we can use the
 *                     // synchronous getProduct() method. Usually, we would use the
 *                     // asynchronous version (see Ext.data.association.BelongsTo).
 *                     var product = orderItem.getProduct();
 *                     output.push(orderItem.get("quantity") + " orders of " + product.get("name"));
 *                 });
 *             });
 *             Ext.Msg.alert('Output:', output.join("<br/>"));
 *         }
 *     });
 *
 * This may be a lot to take in - basically a User has many Orders, each of which is composed of several OrderItems.
 * Finally, each OrderItem has a single Product. This allows us to consume data like this (_users.json_):
 *
 *     {
 *         "users": [
 *             {
 *                 "id": 123,
 *                 "name": "Ed",
 *                 "orders": [
 *                     {
 *                         "id": 50,
 *                         "total": 100,
 *                         "order_items": [
 *                             {
 *                                 "id"      : 20,
 *                                 "price"   : 40,
 *                                 "quantity": 2,
 *                                 "product" : {
 *                                     "id": 1000,
 *                                     "name": "MacBook Pro"
 *                                 }
 *                             },
 *                             {
 *                                 "id"      : 21,
 *                                 "price"   : 20,
 *                                 "quantity": 3,
 *                                 "product" : {
 *                                     "id": 1001,
 *                                     "name": "iPhone"
 *                                 }
 *                             }
 *                         ]

 *                 ]
 *             }
 *         ]
 *     }
 *
 * The JSON response is deeply nested - it returns all Users (in this case just 1 for simplicity's sake), all of the
 * Orders for each User (again just 1 in this case), all of the OrderItems for each Order (2 order items in this case),
 * and finally the Product associated with each OrderItem.
 *
 * Running the code above results in the following:
 *
 *     Orders for Ed:
 *     Order ID: 50, which contains items:
 *     2 orders of MacBook Pro
 *     3 orders of iPhone

/**
 * The JSON Reader is used by a Proxy to read a server response that is sent back in JSON format. This usually happens
 * as a result of loading a Store - for example we might create something like this:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['id', 'name', 'email']
 *         }
 *     });
 *
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'User',
 *         proxy: {
 *             type: 'ajax',
 *             url : 'users.json',
 *             reader: {
 *                 type: 'json'
 *             }
 *         }
 *     });
 *
 * The example above creates a 'User' model. Models are explained in the {@link Ext.data.Model Model} docs if you're not
 * already familiar with them.
 *
 * We created the simplest type of JSON Reader possible by simply telling our {@link Ext.data.Store Store}'s {@link
 * Ext.data.proxy.Proxy Proxy} that we want a JSON Reader. The Store automatically passes the configured model to the
 * Store, so it is as if we passed this instead:
 *
 *     reader: {
 *         type : 'json',
 *         model: 'User'
 *     }
 *
 * The reader we set up is ready to read data from our server - at the moment it will accept a response like this:
 *
 *     [
 *         {
 *             "id": 1,
 *             "name": "Ed Spencer",
 *             "email": "ed@sencha.com"
 *         },
 *         {
 *             "id": 2,
 *             "name": "Abe Elias",
 *             "email": "abe@sencha.com"
 *         }
 *     ]
 *
 * ## Reading other JSON formats
 *
 * If you already have your JSON format defined and it doesn't look quite like what we have above, you can usually pass
 * JsonReader a couple of configuration options to make it parse your format. For example, we can use the
 * {@link #rootProperty} configuration to parse data that comes back like this:
 *
 *     {
 *         "users": [
 *            {
 *                "id": 1,
 *                "name": "Ed Spencer",
 *                "email": "ed@sencha.com"
 *            },
 *            {
 *                "id": 2,
 *                "name": "Abe Elias",
 *                "email": "abe@sencha.com"
 *            }
 *         ]
 *     }
 *
 * To parse this we just pass in a {@link #rootProperty} configuration that matches the 'users' above:
 *
 *     reader: {
 *         type: 'json',
 *         rootProperty: 'users'
 *     }
 *
 * Sometimes the JSON structure is even more complicated. Document databases like CouchDB often provide metadata around
 * each record inside a nested structure like this:
 *
 *     {
 *         "total": 122,
 *         "offset": 0,
 *         "users": [
 *             {
 *                 "id": "ed-spencer-1",
 *                 "value": 1,
 *                 "user": {
 *                     "id": 1,
 *                     "name": "Ed Spencer",
 *                     "email": "ed@sencha.com"
 *                 }
 *             }
 *         ]
 *     }
 *
 * In the case above the record data is nested an additional level inside the "users" array as each "user" item has
 * additional metadata surrounding it ('id' and 'value' in this case). To parse data out of each "user" item in the JSON
 * above we need to specify the {@link #record} configuration like this:
 *
 *     reader: {
 *         type: 'json',
 *         record: 'user',
 *         rootProperty: 'users'
 *     }
 *
 * ## Response MetaData
 *
 * The server can return metadata in its response, in addition to the record data, that describe attributes
 * of the data set itself or are used to reconfigure the Reader. To pass metadata in the response you simply
 * add a `metaData` attribute to the root of the response data. The metaData attribute can contain anything,
 * but supports a specific set of properties that are handled by the Reader if they are present:
 *
 * - {@link #idProperty}: property name for the primary key field of the data
 * - {@link #rootProperty}: the property name of the root response node containing the record data
 * - {@link #totalProperty}: property name for the total number of records in the data
 * - {@link #successProperty}: property name for the success status of the response
 * - {@link #messageProperty}: property name for an optional response message
 * - {@link Ext.data.Model#cfg-fields fields}: Config used to reconfigure the Model's fields before converting the
 *   response data into records
 *
 * An initial Reader configuration containing all of these properties might look like this ("fields" would be
 * included in the Model definition, not shown):
 *
 *     reader: {
 *         type: 'json',
 *         idProperty: 'id',
 *         rootProperty: 'root',
 *         totalProperty: 'total',
 *         successProperty: 'success',
 *         messageProperty: 'message'
 *     }
 *
 * If you were to pass a response object containing attributes different from those initially defined above, you could
 * use the `metaData` attribute to reconfigure the Reader on the fly. For example:
 *
 *     {
 *         "count": 1,
 *         "ok": true,
 *         "msg": "Users found",
 *         "users": [{
 *             "userId": 123,
 *             "name": "Ed Spencer",
 *             "email": "ed@sencha.com"
 *         }],
 *         "metaData": {
 *             "idProperty": 'userId',
 *             "rootProperty": "users",
 *             "totalProperty": 'count',
 *             "successProperty": 'ok',
 *             "messageProperty": 'msg'
 *         }
 *     }
 *
 * You can also place any other arbitrary data you need into the `metaData` attribute which will be ignored by the Reader,
 * but will be accessible via the Reader's {@link #metaData} property. Application code can then process the passed
 * metadata in any way it chooses.
 *
 * A simple example for how this can be used would be customizing the fields for a Model that is bound to a grid. By passing
 * the `fields` property the Model will be automatically updated by the Reader internally, but that change will not be
 * reflected automatically in the grid unless you also update the column configuration. You could do this manually, or you
 * could simply pass a standard grid column config object as part of the `metaData` attribute
 * and then pass that along to the grid. Here's a very simple example for how that could be accomplished:
 *
 *     // response format:
 *     {
 *         ...
 *         "metaData": {
 *             "fields": [
 *                 { "name": "userId", "type": "int" },
 *                 { "name": "name", "type": "string" },
 *                 { "name": "birthday", "type": "date", "dateFormat": "Y-j-m" },
 *             ],
 *             "columns": [
 *                 { "text": "User ID", "dataIndex": "userId", "width": 40 },
 *                 { "text": "User Name", "dataIndex": "name", "flex": 1 },
 *                 { "text": "Birthday", "dataIndex": "birthday", "flex": 1, "format": 'Y-j-m', "xtype": "datecolumn" }
 *             ]
 *         }
 *     }

 * @author Ed Spencer
 *
 * Proxies are used by {@link Ext.data.Store Stores} to handle the loading and saving of {@link Ext.data.Model Model}
 * data. Usually developers will not need to create or interact with proxies directly.
 *
 * # Types of Proxy
 *
 * There are two main types of Proxy - {@link Ext.data.proxy.Client Client} and {@link Ext.data.proxy.Server Server}.
 * The Client proxies save their data locally and include the following subclasses:
 *
 * - {@link Ext.data.proxy.LocalStorage LocalStorageProxy} - saves its data to localStorage if the browser supports it
 * - {@link Ext.data.proxy.Memory MemoryProxy} - holds data in memory only, any data is lost when the page is refreshed
 *
 * The Server proxies save their data by sending requests to some remote server. These proxies include:
 *
 * - {@link Ext.data.proxy.Ajax Ajax} - sends requests to a server on the same domain
 * - {@link Ext.data.proxy.JsonP JsonP} - uses JSON-P to send requests to a server on a different domain
 *
 * Proxies operate on the principle that all operations performed are either Create, Read, Update or Delete. These four
 * operations are mapped to the methods {@link #create}, {@link #read}, {@link #update} and {@link #destroy}
 * respectively. Each Proxy subclass implements these functions.
 *
 * The CRUD methods each expect an {@link Ext.data.Operation Operation} object as the sole argument. The Operation
 * encapsulates information about the action the Store wishes to perform, the {@link Ext.data.Model model} instances
 * that are to be modified, etc. See the {@link Ext.data.Operation Operation} documentation for more details. Each CRUD
 * method also accepts a callback function to be called asynchronously on completion.
 *
 * Proxies also support batching of Operations via a {@link Ext.data.Batch batch} object, invoked by the {@link #batch}
 * method.

/**
 * DataView makes it easy to create lots of components dynamically, usually based off a {@link Ext.data.Store Store}.
 * It's great for rendering lots of data from your server backend or any other data source and is what powers
 * components like {@link Ext.List}.
 *
 * Use DataView whenever you want to show sets of the same component many times, for examples in apps like these:
 *
 * - List of messages in an email app
 * - Showing latest news/tweets
 * - Tiled set of albums in an HTML5 music player
 *
 * # Creating a Simple DataView
 *
 * At its simplest, a DataView is just a Store full of data and a simple template that we use to render each item:
 *
 *     @example miniphone preview
 *     var touchTeam = Ext.create('Ext.DataView', {
 *         fullscreen: true,
 *         store: {
 *             fields: ['name', 'age'],
 *             data: [
 *                 {name: 'Jamie',  age: 100},
 *                 {name: 'Rob',   age: 21},
 *                 {name: 'Tommy', age: 24},
 *                 {name: 'Jacky', age: 24},
 *                 {name: 'Ed',   age: 26}
 *             ]
 *         },
 *
 *         itemTpl: '<div>{name} is {age} years old</div>'
 *     });
 *
 * Here we just defined everything inline so it's all local with nothing being loaded from a server. For each of the 5
 * data items defined in our Store, DataView will render a {@link Ext.Component Component} and pass in the name and age
 * data. The component will use the tpl we provided above, rendering the data in the curly bracket placeholders we
 * provided.
 *
 * Because DataView is integrated with Store, any changes to the Store are immediately reflected on the screen. For
 * example, if we add a new record to the Store it will be rendered into our DataView:
 *
 *     touchTeam.getStore().add({
 *         name: 'Abe Elias',
 *         age: 33
 *     });
 *
 * We didn't have to manually update the DataView, it's just automatically updated. The same happens if we modify one
 * of the existing records in the Store:
 *
 *     touchTeam.getStore().getAt(0).set('age', 42);
 *
 * This will get the first record in the Store (Jamie), change the age to 42 and automatically update what's on the
 * screen.
 *
 *     @example miniphone
 *     var touchTeam = Ext.create('Ext.DataView', {
 *         fullscreen: true,
 *         store: {
 *             fields: ['name', 'age'],
 *             data: [
 *                 {name: 'Jamie',  age: 100},
 *                 {name: 'Rob',   age: 21},
 *                 {name: 'Tommy', age: 24},
 *                 {name: 'Jacky', age: 24},
 *                 {name: 'Ed',   age: 26}
 *             ]
 *         },
 *
 *         itemTpl: '<div>{name} is {age} years old</div>'
 *     });
 *
 *     touchTeam.getStore().add({
 *         name: 'Abe Elias',
 *         age: 33
 *     });
 *
 *     touchTeam.getStore().getAt(0).set('age', 42);
 *
 * # Loading data from a server
 *
 * We often want to load data from our server or some other web service so that we don't have to hard code it all
 * locally. Let's say we want to load some horror movies from Rotten Tomatoes into a DataView, and for each one
 * render the cover image and title. To do this all we have to do is grab an api key from rotten tomatoes (http://developer.rottentomatoes.com/)
 * and modify the {@link #store} and {@link #itemTpl} a little:
 *
 *     @example portrait
 *     Ext.create('Ext.DataView', {
 *         fullscreen: true,
 *         store: {
 *             autoLoad: true,
 *             fields: ['id', 'title',
 *              {
 *                  name:'thumbnail_image',
 *                  convert: function(v, record) {return record.raw.posters.thumbnail; }
 *              }],
 *
 *             proxy: {
 *                 type: 'jsonp',
 *                 // Modify this line with your API key, pretty please...
 *                 url: 'http://api.rottentomatoes.com/api/public/v1.0/movies.json?apikey=hbjgfgryw8tygxztr5wtag3u&q=Horror',
 *
 *                 reader: {
 *                     type: 'json',
 *                     rootProperty: 'results'
 *                 }
 *             }
 *         },
 *
 *         itemTpl: '<img src="{thumbnail_image}" /><p>{title}</p><div style="clear: both"></div>'
 *     });
 *
 * The Store no longer has hard coded data, instead we've provided a {@link Ext.data.proxy.Proxy Proxy}, which fetches
 * the data for us. In this case we used a JSON-P proxy so that we can load from Twitter's JSON-P search API. We also
 * specified the fields present for each tweet, and used Store's {@link Ext.data.Store#autoLoad autoLoad} configuration
 * to load automatically. Finally, we configured a Reader to decode the response from Twitter, telling it to expect
 * JSON and that the tweets can be found in the 'results' part of the JSON response.
 *
 * The last thing we did is update our template to render the image, Twitter username and message. All we need to do
 * now is add a little CSS to style the list the way we want it and we end up with a very basic Twitter viewer. Click
 * the preview button on the example above to see it in action.

/**
 * @class Ext.data.Types
 *
 * This is a static class containing the system-supplied data types which may be given to a {@link Ext.data.Field Field}.
 *
 * The properties in this class are used as type indicators in the {@link Ext.data.Field Field} class, so to
 * test whether a Field is of a certain type, compare the {@link Ext.data.Field#type type} property against properties
 * of this class.
 *
 * Developers may add their own application-specific data types to this class. Definition names must be UPPERCASE.
 * each type definition must contain three properties:
 *
 * - `convert`: {Function} - A function to convert raw data values from a data block into the data
 * to be stored in the Field. The function is passed the following parameters:
 *   + `v`: {Mixed} - The data value as read by the Reader, if `undefined` will use
 * the configured `{@link Ext.data.Field#defaultValue defaultValue}`.
 *   + `rec`: {Mixed} - The data object containing the row as read by the Reader.
 * Depending on the Reader type, this could be an Array ({@link Ext.data.reader.Array ArrayReader}), an object
 * ({@link Ext.data.reader.Json JsonReader}), or an XML element.
 * - `sortType`: {Function} - A function to convert the stored data into comparable form, as defined by {@link Ext.data.SortTypes}.
 * - `type`: {String} - A textual data type name.
 *
 * For example, to create a VELatLong field (See the Microsoft Bing Mapping API) containing the latitude/longitude value of a datapoint on a map from a JsonReader data block
 * which contained the properties `lat` and `long`, you would define a new data type like this:
 *
 *     // Add a new Field data type which stores a VELatLong object in the Record.
 *     Ext.data.Types.VELATLONG = {
 *         convert: function(v, data) {
 *             return new VELatLong(data.lat, data.long);
 *         },
 *         sortType: function(v) {
 *             return v.Latitude;  // When sorting, order by latitude
 *         },
 *         type: 'VELatLong'
 *     };
 *
 * Then, when declaring a Model, use:
 *
 *     var types = Ext.data.Types; // allow shorthand type access
 *     Ext.define('Unit', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 { name: 'unitName', mapping: 'UnitName' },
 *                 { name: 'curSpeed', mapping: 'CurSpeed', type: types.INT },
 *                 { name: 'latitude', mapping: 'lat', type: types.FLOAT },
 *                 { name: 'position', type: types.VELATLONG }
 *             ]
 *         }

 * Fields are used to define what a Model is. They aren't instantiated directly - instead, when we create a class that
 * extends {@link Ext.data.Model}, it will automatically create a Field instance for each field configured in a {@link
 * Ext.data.Model Model}. For example, we might set up a model like this:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 'name', 'email',
 *                 {name: 'age', type: 'int'},
 *                 {name: 'gender', type: 'string', defaultValue: 'Unknown'}
 *             ]
 *         }
 *     });
 *
 * Four fields will have been created for the User Model - name, email, age, and gender. Note that we specified a couple
 * of different formats here; if we only pass in the string name of the field (as with name and email), the field is set
 * up with the 'auto' type. It's as if we'd done this instead:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 {name: 'name', type: 'auto'},
 *                 {name: 'email', type: 'auto'},
 *                 {name: 'age', type: 'int'},
 *                 {name: 'gender', type: 'string', defaultValue: 'Unknown'}
 *             ]
 *         }
 *     });
 *
 * # Types and conversion
 *
 * The {@link #type} is important - it's used to automatically convert data passed to the field into the correct format.
 * In our example above, the name and email fields used the 'auto' type and will just accept anything that is passed
 * into them. The 'age' field had an 'int' type however, so if we passed 25.4 this would be rounded to 25.
 *
 * Sometimes a simple type isn't enough, or we want to perform some processing when we load a Field's data. We can do
 * this using a {@link #convert} function. Here, we're going to create a new field based on another:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 'name', 'email',
 *                 {name: 'age', type: 'int'},
 *                 {name: 'gender', type: 'string', defaultValue: 'Unknown'},
 *
 *                 {
 *                     name: 'firstName',
 *                     convert: function(value, record) {
 *                         var fullName  = record.get('name'),
 *                             splits    = fullName.split(" "),
 *                             firstName = splits[0];
 *
 *                         return firstName;
 *                     }
 *                 }
 *             ]
 *         }
 *     });
 *
 * Now when we create a new User, the firstName is populated automatically based on the name:
 *
 *     var ed = Ext.create('User', {name: 'Ed Spencer'});
 *
 *     console.log(ed.get('firstName')); //logs 'Ed', based on our convert function
 *
 * In fact, if we log out all of the data inside ed, we'll see this:
 *
 *     console.log(ed.data);
 *
 *     //outputs this:
 *     {
 *         age: 0,
 *         email: "",
 *         firstName: "Ed",
 *         gender: "Unknown",
 *         name: "Ed Spencer"
 *     }
 *
 * The age field has been given a default of zero because we made it an int type. As an auto field, email has defaulted
 * to an empty string. When we registered the User model we set gender's {@link #defaultValue} to 'Unknown' so we see
 * that now. Let's correct that and satisfy ourselves that the types work as we expect:
 *
 *     ed.set('gender', 'Male');
 *     ed.get('gender'); //returns 'Male'
 *
 *     ed.set('age', 25.4);
 *     ed.get('age'); //returns 25 - we wanted an int, not a float, so no decimal places allowed

 *
 * The ModelManager keeps track of all {@link Ext.data.Model} types defined in your application.
 *
 * ## Creating Model Instances
 *
 * Model instances can be created by using the {@link Ext.ClassManager#create Ext.create} method. Ext.create replaces
 * the deprecated {@link #create Ext.ModelManager.create} method. It is also possible to create a model instance
 * this by using the Model type directly. The following 3 snippets are equivalent:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['first', 'last']
 *         }
 *     });
 *
 *     // method 1, create using Ext.create (recommended)
 *     Ext.create('User', {
 *         first: 'Ed',
 *         last: 'Spencer'
 *     });
 *
 *     // method 2, create on the type directly
 *     new User({
 *         first: 'Ed',
 *         last: 'Spencer'
 *     });
 *
 *     // method 3, create through the manager (deprecated)
 *     Ext.ModelManager.create({
 *         first: 'Ed',
 *         last: 'Spencer'
 *     }, 'User');
 *
 * ## Accessing Model Types
 *
 * A reference to a Model type can be obtained by using the {@link #getModel} function. Since models types
 * are normal classes, you can access the type directly. The following snippets are equivalent:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['first', 'last']
 *         }
 *     });
 *
 *     // method 1, access model type through the manager
 *     var UserType = Ext.ModelManager.getModel('User');
 *
 *     // method 2, reference the type directly
 *     var UserType = User;

/**
 * @author Ed Spencer
 *
 * AjaxProxy is one of the most widely-used ways of getting data into your application. It uses AJAX
 * requests to load data from the server, usually to be placed into a {@link Ext.data.Store Store}.
 * Let's take a look at a typical setup. Here we're going to set up a Store that has an AjaxProxy.
 * To prepare, we'll also set up a {@link Ext.data.Model Model}:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['id', 'name', 'email']
 *         }
 *     });
 *
 *     // The Store contains the AjaxProxy as an inline configuration
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'User',
 *         proxy: {
 *             type: 'ajax',
 *             url : 'users.json'
 *         }
 *     });
 *
 *     store.load();
 *
 * Our example is going to load user data into a Store, so we start off by defining a
 * {@link Ext.data.Model Model} with the fields that we expect the server to return. Next we set up
 * the Store itself, along with a {@link Ext.data.Store#proxy proxy} configuration. This
 * configuration was automatically turned into an Ext.data.proxy.Ajax instance, with the url we
 * specified being passed into AjaxProxy's constructor. It's as if we'd done this:
 *
 *     Ext.create('Ext.data.proxy.Ajax', {
 *         config: {
 *             url: 'users.json',
 *             model: 'User',
 *             reader: 'json'
 *         }
 *     });
 *
 * A couple of extra configurations appeared here - {@link #model} and {@link #reader}. These are
 * set by default when we create the proxy via the Store - the Store already knows about the Model,
 * and Proxy's default {@link Ext.data.reader.Reader Reader} is {@link Ext.data.reader.Json JsonReader}.
 *
 * Now when we call store.load(), the AjaxProxy springs into action, making a request to the url we
 * configured ('users.json' in this case). As we're performing a read, it sends a GET request to
 * that url (see {@link #actionMethods} to customize this - by default any kind of read will be sent
 * as a GET request and any kind of write will be sent as a POST request).
 *
 * ## Limitations
 *
 * AjaxProxy cannot be used to retrieve data from other domains. If your application is running on
 * http://domainA.com it cannot load data from http://domainB.com because browsers have a built-in
 * security policy that prohibits domains talking to each other via AJAX.
 *
 * If you need to read data from another domain and can't set up a proxy server (some software that
 * runs on your own domain's web server and transparently forwards requests to http://domainB.com,
 * making it look like they actually came from http://domainA.com), you can use
 * {@link Ext.data.proxy.JsonP} and a technique known as JSON-P (JSON with Padding), which can help
 * you get around the problem so long as the server on http://domainB.com is set up to support
 * JSON-P responses. See {@link Ext.data.proxy.JsonP JsonPProxy}'s introduction docs for more details.
 *
 * ## Readers and Writers
 *
 * AjaxProxy can be configured to use any type of {@link Ext.data.reader.Reader Reader} to decode
 * the server's response. If no Reader is supplied, AjaxProxy will default to using a
 * {@link Ext.data.reader.Json JsonReader}. Reader configuration can be passed in as a simple
 * object, which the Proxy automatically turns into a {@link Ext.data.reader.Reader Reader} instance:
 *
 *     var proxy = Ext.create('Ext.data.proxy.Ajax', {
 *         config: {
 *             model: 'User',
 *             reader: {
 *                 type: 'xml',
 *                 root: 'users'
 *             }
 *         }
 *     });
 *
 *     proxy.getReader(); //returns an {@link Ext.data.reader.Xml XmlReader} instance based on the config we supplied
 *
 * ## Url generation
 *
 * AjaxProxy automatically inserts any sorting, filtering, paging and grouping options into the url
 * it generates for each request. These are controlled with the following configuration options:
 *
 * - {@link #pageParam} - controls how the page number is sent to the server (see also
 *   {@link #startParam} and {@link #limitParam})
 * - {@link #sortParam} - controls how sort information is sent to the server
 * - {@link #groupParam} - controls how grouping information is sent to the server
 * - {@link #filterParam} - controls how filter information is sent to the server
 *
 * Each request sent by AjaxProxy is described by an {@link Ext.data.Operation Operation}. To see
 * how we can customize the generated urls, let's say we're loading the Proxy with the following
 * Operation:
 *
 *     var operation = Ext.create('Ext.data.Operation', {
 *         action: 'read',
 *         page  : 2
 *     });
 *
 * Now we'll issue the request for this Operation by calling {@link #read}:
 *
 *     var proxy = Ext.create('Ext.data.proxy.Ajax', {
 *         url: '/users'
 *     });
 *
 *     proxy.read(operation); // GET /users?page=2
 *
 * Easy enough - the Proxy just copied the page property from the Operation. We can customize how
 * this page data is sent to the server:
 *
 *     var proxy = Ext.create('Ext.data.proxy.Ajax', {
 *         url: '/users',
 *         pageParam: 'pageNumber'
 *     });
 *
 *     proxy.read(operation); // GET /users?pageNumber=2
 *
 * Alternatively, our Operation could have been configured to send start and limit parameters
 * instead of page:
 *
 *     var operation = Ext.create('Ext.data.Operation', {
 *         action: 'read',
 *         start : 50,
 *         limit : 25
 *     });
 *
 *     var proxy = Ext.create('Ext.data.proxy.Ajax', {
 *         url: '/users'
 *     });
 *
 *     proxy.read(operation); // GET /users?start=50&limit;=25
 *
 * Again we can customize this url:
 *
 *     var proxy = Ext.create('Ext.data.proxy.Ajax', {
 *         url: '/users',
 *         startParam: 'startIndex',
 *         limitParam: 'limitIndex'
 *     });
 *
 *     proxy.read(operation); // GET /users?startIndex=50&limitIndex;=25
 *
 * AjaxProxy will also send sort and filter information to the server. Let's take a look at how this
 * looks with a more expressive Operation object:
 *
 *     var operation = Ext.create('Ext.data.Operation', {
 *         action: 'read',
 *         sorters: [
 *             Ext.create('Ext.util.Sorter', {
 *                 property : 'name',
 *                 direction: 'ASC'
 *             }),
 *             Ext.create('Ext.util.Sorter', {
 *                 property : 'age',
 *                 direction: 'DESC'
 *             })
 *         ],
 *         filters: [
 *             Ext.create('Ext.util.Filter', {
 *                 property: 'eyeColor',
 *                 value   : 'brown'
 *             })
 *         ]
 *     });
 *
 * This is the type of object that is generated internally when loading a {@link Ext.data.Store Store}
 * with sorters and filters defined. By default the AjaxProxy will JSON encode the sorters and
 * filters, resulting in something like this (note that the url is escaped before sending the
 * request, but is left unescaped here for clarity):
 *
 *     var proxy = Ext.create('Ext.data.proxy.Ajax', {
 *         url: '/users'
 *     });
 *
 *     proxy.read(operation); // GET /users?sort=[{"property":"name","direction":"ASC"},{"property":"age","direction":"DESC"}]&filter;=[{"property":"eyeColor","value":"brown"}]
 *
 * We can again customize how this is created by supplying a few configuration options. Let's say
 * our server is set up to receive sorting information is a format like "sortBy=name#ASC,age#DESC".
 * We can configure AjaxProxy to provide that format like this:
 *
 *      var proxy = Ext.create('Ext.data.proxy.Ajax', {
 *          url: '/users',
 *          sortParam: 'sortBy',
 *          filterParam: 'filterBy',
 *
 *          // our custom implementation of sorter encoding - turns our sorters into "name#ASC,age#DESC"
 *          encodeSorters: function(sorters) {
 *              var length   = sorters.length,
 *                  sortStrs = [],
 *                  sorter, i;
 *
 *              for (i = 0; i < length; i++) {
 *                  sorter = sorters[i];
 *
 *                  sortStrs[i] = sorter.property + '#' + sorter.direction;
 *              }
 *
 *              return sortStrs.join(",");
 *          }
 *      });
 *
 *      proxy.read(operation); // GET /users?sortBy=name#ASC,age#DESC&filterBy;=[{"property":"eyeColor","value":"brown"}]
 *
 * We can also provide a custom {@link #encodeFilters} function to encode our filters.

 *
 * Associations enable you to express relationships between different {@link Ext.data.Model Models}. Let's say we're
 * writing an ecommerce system where Users can make Orders - there's a relationship between these Models that we can
 * express like this:
 *
 *     Ext.define('MyApp.model.User', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: ['id', 'name', 'email'],
 *             hasMany: {
 *                 model: 'MyApp.model.Order',
 *                 name: 'orders'
 *             }
 *         }
 *     });
 *
 *     Ext.define('MyApp.model.Order', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: ['id', 'user_id', 'status', 'price'],
 *             belongsTo: 'MyApp.model.User'
 *         }
 *     });
 *
 * We've set up two models - User and Order - and told them about each other. You can set up as many associations on
 * each Model as you need using the two default types - {@link Ext.data.association.HasMany hasMany} and
 * {@link Ext.data.association.BelongsTo belongsTo}. There's much more detail on the usage of each of those inside their
 * documentation pages. If you're not familiar with Models already, {@link Ext.data.Model there is plenty on those too}.
 *
 * ## Further Reading

 *
 * ### Self-associating Models
 *
 * We can also have models that create parent/child associations between the same type. Below is an example, where
 * groups can be nested inside other groups:
 *
 *     // Server Data
 *     {
 *         "groups": {
 *             "id": 10,
 *             "parent_id": 100,

/**
 * General purpose inflector class that {@link #pluralize pluralizes}, {@link #singularize singularizes} and 
 * {@link #ordinalize ordinalizes} words. Sample usage:
 *
 *     // turning singular words into plurals
 *     Ext.util.Inflector.pluralize('word'); // 'words'
 *     Ext.util.Inflector.pluralize('person'); // 'people'
 *     Ext.util.Inflector.pluralize('sheep'); // 'sheep'
 *
 *     // turning plurals into singulars
 *     Ext.util.Inflector.singularize('words'); // 'word'
 *     Ext.util.Inflector.singularize('people'); // 'person'
 *     Ext.util.Inflector.singularize('sheep'); // 'sheep'
 *
 *     // ordinalizing numbers
 *     Ext.util.Inflector.ordinalize(11); // "11th"
 *     Ext.util.Inflector.ordinalize(21); // "21st"
 *     Ext.util.Inflector.ordinalize(1043); // "1043rd"
 *
 * ## Customization
 *
 * The Inflector comes with a default set of US English pluralization rules. These can be augmented with additional
 * rules if the default rules do not meet your application's requirements, or swapped out entirely for other languages.
 * Here is how we might add a rule that pluralizes "ox" to "oxen":
 *
 *     Ext.util.Inflector.plural(/^(ox)$/i, "$1en");
 *
 * Each rule consists of two items - a regular expression that matches one or more rules, and a replacement string.
 * In this case, the regular expression will only match the string "ox", and will replace that match with "oxen".
 * Here's how we could add the inverse rule:
 *
 *     Ext.util.Inflector.singular(/^(ox)en$/i, "$1");
 *
 * __Note:__ The ox/oxen rules are present by default.

/**
 * Represents a one-to-many relationship between two models. Usually created indirectly via a model definition:
 *
 *     Ext.define('Product', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 {name: 'id',      type: 'int'},
 *                 {name: 'user_id', type: 'int'},
 *                 {name: 'name',    type: 'string'}
 *             ]
 *         }
 *     });
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 {name: 'id',   type: 'int'},
 *                 {name: 'name', type: 'string'}
 *             ],
 *             // we can use the hasMany shortcut on the model to create a hasMany association
 *             hasMany: {model: 'Product', name: 'products'}
 *         }
 *     });
 *
 * Above we created Product and User models, and linked them by saying that a User hasMany Products. This gives us a new
 * function on every User instance, in this case the function is called 'products' because that is the name we specified
 * in the association configuration above.
 *
 * This new function returns a specialized {@link Ext.data.Store Store} which is automatically filtered to load only
 * Products for the given model instance:
 *
 *     //first, we load up a User with id of 1
 *     var user = Ext.create('User', {id: 1, name: 'Ed'});
 *
 *     //the user.products function was created automatically by the association and returns a {@link Ext.data.Store Store}
 *     //the created store is automatically scoped to the set of Products for the User with id of 1
 *     var products = user.products();
 *
 *     //we still have all of the usual Store functions, for example it's easy to add a Product for this User
 *     products.add({
 *         name: 'Another Product'
 *     });
 *
 *     //saves the changes to the store - this automatically sets the new Product's user_id to 1 before saving
 *     products.sync();
 *
 * The new Store is only instantiated the first time you call products() to conserve memory and processing time, though
 * calling products() a second time returns the same store instance.
 *
 * _Custom filtering_
 *
 * The Store is automatically furnished with a filter - by default this filter tells the store to only return records
 * where the associated model's foreign key matches the owner model's primary key. For example, if a User with ID = 100
 * hasMany Products, the filter loads only Products with user_id == 100.
 *
 * Sometimes we want to filter by another field - for example in the case of a Twitter search application we may have
 * models for Search and Tweet:
 *
 *     Ext.define('Search', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 'id', 'query'
 *             ],
 *
 *             hasMany: {
 *                 model: 'Tweet',
 *                 name : 'tweets',
 *                 filterProperty: 'query'
 *             }
 *         }
 *     });
 *
 *     Ext.define('Tweet', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 'id', 'text', 'from_user'
 *             ]
 *         }
 *     });
 *
 *     //returns a Store filtered by the filterProperty
 *     var store = new Search({query: 'Sencha Touch'}).tweets();
 *
 * The tweets association above is filtered by the query property by setting the {@link #filterProperty}, and is
 * equivalent to this:
 *
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'Tweet',
 *         filters: [
 *             {
 *                 property: 'query',
 *                 value   : 'Sencha Touch'
 *             }
 *         ]
 *     });

 *
 * Represents a many to one association with another model. The owner model is expected to have
 * a foreign key which references the primary key of the associated model:
 *
 *     Ext.define('Category', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 { name: 'id',   type: 'int' },
 *                 { name: 'name', type: 'string' }
 *             ]
 *         }
 *     });
 *
 *     Ext.define('Product', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 { name: 'id',          type: 'int' },
 *                 { name: 'category_id', type: 'int' },
 *                 { name: 'name',        type: 'string' }
 *             ],
 *             // we can use the belongsTo shortcut on the model to create a belongsTo association
 *             belongsTo: {
 *                 model: 'Category'
 *             }
 *         }
 *     });
 *
 * In the example above we have created models for Products and Categories, and linked them together
 * by saying that each Product belongs to a Category. This automatically links each Product to a Category
 * based on the Product's category_id, and provides new functions on the Product model:
 *
 * ## Generated getter function
 *
 * The first function that is added to the owner model is a getter function:
 *
 *     var product = new Product({
 *         id: 100,
 *         category_id: 20,
 *         name: 'Sneakers'
 *     });
 *
 *     product.getCategory(function(category, operation) {
 *         // do something with the category object
 *         alert(category.get('id')); // alerts 20
 *     }, this);
 *
 * The getCategory function was created on the Product model when we defined the association. This uses the
 * Category's configured {@link Ext.data.proxy.Proxy proxy} to load the Category asynchronously, calling the provided
 * callback when it has loaded.
 *
 * The new getCategory function will also accept an object containing success, failure and callback properties
 * - callback will always be called, success will only be called if the associated model was loaded successfully
 * and failure will only be called if the associated model could not be loaded:
 *
 *     product.getCategory({
 *         reload: true, // force a reload if the owner model is already cached
 *         callback: function(category, operation) {}, // a function that will always be called
 *         success : function(category, operation) {}, // a function that will only be called if the load succeeded
 *         failure : function(category, operation) {}, // a function that will only be called if the load did not succeed
 *         scope   : this // optionally pass in a scope object to execute the callbacks in
 *     });
 *
 * In each case above the callbacks are called with two arguments - the associated model instance and the
 * {@link Ext.data.Operation operation} object that was executed to load that instance. The Operation object is
 * useful when the instance could not be loaded.
 *
 * Once the getter has been called on the model, it will be cached if the getter is called a second time. To
 * force the model to reload, specify reload: true in the options object.
 *
 * ## Generated setter function
 *
 * The second generated function sets the associated model instance - if only a single argument is passed to
 * the setter then the following two calls are identical:
 *
 *     // this call...
 *     product.setCategory(10);
 *
 *     // is equivalent to this call:
 *     product.set('category_id', 10);
 *
 * An instance of the owner model can also be passed as a parameter.
 *
 * If we pass in a second argument, the model will be automatically saved and the second argument passed to
 * the owner model's {@link Ext.data.Model#save save} method:
 *
 *     product.setCategory(10, function(product, operation) {
 *         // the product has been saved
 *         alert(product.get('category_id')); //now alerts 10
 *     });
 *
 *     //alternative syntax:
 *     product.setCategory(10, {
 *         callback: function(product, operation) {}, // a function that will always be called
 *         success : function(product, operation) {}, // a function that will only be called if the load succeeded
 *         failure : function(product, operation) {}, // a function that will only be called if the load did not succeed
 *         scope   : this //optionally pass in a scope object to execute the callbacks in
 *     });
 *
 * ## Customization
 *
 * Associations reflect on the models they are linking to automatically set up properties such as the
 * {@link #primaryKey} and {@link #foreignKey}. These can alternatively be specified:
 *
 *     Ext.define('Product', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 // ...
 *             ],
 *
 *             belongsTo: {
 *                 model     : 'Category',
 *                 primaryKey: 'unique_key',
 *                 foreignKey: 'cat_id'
 *             }
 *         }
 *     });
 *
 * Here we replaced the default primary key (defaults to 'id') and foreign key (calculated as 'category_id')
 * with our own settings. Usually this will not be needed.

 *
 * In the example above we have created models for People and Addresses, and linked them together
 * by saying that each Person has a single Address. This automatically links each Person to an Address
 * based on the Persons address_id, and provides new functions on the Person model:
 *
 * ## Generated getter function
 *
 * The first function that is added to the owner model is a getter function:
 *
 *     var person = Ext.create('Person', {
 *         id: 100,
 *         address_id: 20,
 *         name: 'John Smith'
 *     });
 *
 *     person.getAddress(function(address, operation) {
 *         // do something with the address object
 *         alert(address.get('id')); // alerts 20
 *     }, this);
 *
 * The getAddress function was created on the Person model when we defined the association. This uses the
 * Persons configured {@link Ext.data.proxy.Proxy proxy} to load the Address asynchronously, calling the provided
 * callback when it has loaded.
 *
 * The new getAddress function will also accept an object containing success, failure and callback properties
 * - callback will always be called, success will only be called if the associated model was loaded successfully
 * and failure will only be called if the associated model could not be loaded:
 *
 *     person.getAddress({
 *         reload: true, // force a reload if the owner model is already cached
 *         callback: function(address, operation) {}, // a function that will always be called
 *         success : function(address, operation) {}, // a function that will only be called if the load succeeded
 *         failure : function(address, operation) {}, // a function that will only be called if the load did not succeed
 *         scope   : this // optionally pass in a scope object to execute the callbacks in
 *     });
 *
 * In each case above the callbacks are called with two arguments - the associated model instance and the
 * {@link Ext.data.Operation operation} object that was executed to load that instance. The Operation object is
 * useful when the instance could not be loaded.
 *
 * Once the getter has been called on the model, it will be cached if the getter is called a second time. To
 * force the model to reload, specify reload: true in the options object.
 *
 * ## Generated setter function
 *
 * The second generated function sets the associated model instance - if only a single argument is passed to
 * the setter then the following two calls are identical:
 *
 *     // this call...
 *     person.setAddress(10);
 *
 *     // is equivalent to this call:
 *     person.set('address_id', 10);
 *
 * An instance of the owner model can also be passed as a parameter.
 *
 * If we pass in a second argument, the model will be automatically saved and the second argument passed to
 * the owner model's {@link Ext.data.Model#save save} method:
 *
 *     person.setAddress(10, function(address, operation) {
 *         // the address has been saved
 *         alert(address.get('address_id')); //now alerts 10
 *     });
 *
 *     //alternative syntax:
 *     person.setAddress(10, {
 *         callback: function(address, operation) {}, // a function that will always be called
 *         success : function(address, operation) {}, // a function that will only be called if the load succeeded
 *         failure : function(address, operation) {}, // a function that will only be called if the load did not succeed
 *         scope   : this //optionally pass in a scope object to execute the callbacks in
 *     });
 *
 * ## Customization
 *
 * Associations reflect on the models they are linking to automatically set up properties such as the
 * {@link #primaryKey} and {@link #foreignKey}. These can alternatively be specified:
 *
 *     Ext.define('Person', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 // ...
 *             ],
 *
 *             hasOne: {
 *                 model     : 'Address', 
 *                 primaryKey: 'unique_id',
 *                 foreignKey: 'addr_id'
 *             }
 *         }
 *     });
 *
 * Here we replaced the default primary key (defaults to 'id') and foreign key (calculated as 'address_id')
 * with our own settings. Usually this will not be needed.

 *
 * A Model represents some object that your application manages. For example, one might define a Model for Users,
 * Products, Cars, or any other real-world object that we want to model in the system. Models are registered via the
 * {@link Ext.data.ModelManager model manager}, and are used by {@link Ext.data.Store stores}, which are in turn used by many
 * of the data-bound components in Ext.
 *
 * Models are defined as a set of fields and any arbitrary methods and properties relevant to the model. For example:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: [
 *                 {name: 'name',  type: 'string'},
 *                 {name: 'age',   type: 'int'},
 *                 {name: 'phone', type: 'string'},
 *                 {name: 'alive', type: 'boolean', defaultValue: true}
 *             ]
 *         },
 *
 *         changeName: function() {
 *             var oldName = this.get('name'),
 *                 newName = oldName + " The Barbarian";
 *
 *             this.set('name', newName);
 *         }
 *     });
 *
 * The fields array is turned into a {@link Ext.util.MixedCollection MixedCollection} automatically by the {@link
 * Ext.data.ModelManager ModelManager}, and all other functions and properties are copied to the new Model's prototype.
 *
 * Now we can create instances of our User model and call any model logic we defined:
 *
 *     var user = Ext.create('User', {
 *         name : 'Conan',
 *         age  : 24,
 *         phone: '555-555-5555'
 *     });
 *
 *     user.changeName();
 *     user.get('name'); // returns "Conan The Barbarian"
 *
 * # Validations
 *
 * Models have built-in support for validations, which are executed against the validator functions in {@link
 * Ext.data.validations} ({@link Ext.data.validations see all validation functions}). Validations are easy to add to
 * models:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: [
 *                 {name: 'name',     type: 'string'},
 *                 {name: 'age',      type: 'int'},
 *                 {name: 'phone',    type: 'string'},
 *                 {name: 'gender',   type: 'string'},
 *                 {name: 'username', type: 'string'},
 *                 {name: 'alive',    type: 'boolean', defaultValue: true}
 *             ],
 *
 *             validations: [
 *                 {type: 'presence',  field: 'age'},
 *                 {type: 'length',    field: 'name',     min: 2},
 *                 {type: 'inclusion', field: 'gender',   list: ['Male', 'Female']},
 *                 {type: 'exclusion', field: 'username', list: ['Admin', 'Operator']},
 *                 {type: 'format',    field: 'username', matcher: /([a-z]+)[0-9]{2,3}/}
 *             ]
 *         }
 *     });
 *
 * The validations can be run by simply calling the {@link #validate} function, which returns a {@link Ext.data.Errors}
 * object:
 *
 *     var instance = Ext.create('User', {
 *         name: 'Ed',
 *         gender: 'Male',
 *         username: 'edspencer'
 *     });
 *
 *     var errors = instance.validate();
 *
 * # Associations
 *
 * Models can have associations with other Models via {@link Ext.data.association.HasOne},
 * {@link Ext.data.association.BelongsTo belongsTo} and {@link Ext.data.association.HasMany hasMany} associations.
 * For example, let's say we're writing a blog administration application which deals with Users, Posts and Comments.
 * We can express the relationships between these models like this:
 *
 *     Ext.define('Post', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: ['id', 'user_id'],
 *             belongsTo: 'User',
 *             hasMany  : {model: 'Comment', name: 'comments'}
 *         }
 *     });
 *
 *     Ext.define('Comment', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: ['id', 'user_id', 'post_id'],
 *             belongsTo: 'Post'
 *         }
 *     });
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: ['id'],
 *             hasMany: [
 *                 'Post',
 *                 {model: 'Comment', name: 'comments'}
 *             ]
 *         }
 *     });
 *
 * See the docs for {@link Ext.data.association.HasOne}, {@link Ext.data.association.BelongsTo} and
 * {@link Ext.data.association.HasMany} for details on the usage and configuration of associations.
 * Note that associations can also be specified like this:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: ['id'],
 *             associations: [
 *                 {type: 'hasMany', model: 'Post',    name: 'posts'},
 *                 {type: 'hasMany', model: 'Comment', name: 'comments'}
 *             ]
 *         }
 *     });
 *
 * # Using a Proxy
 *
 * Models are great for representing types of data and relationships, but sooner or later we're going to want to load or
 * save that data somewhere. All loading and saving of data is handled via a {@link Ext.data.proxy.Proxy Proxy}, which
 * can be set directly on the Model:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *
 *         config: {
 *             fields: ['id', 'name', 'email'],
 *             proxy: {
 *                 type: 'rest',
 *                 url : '/users'
 *             }
 *         }
 *     });
 *
 * Here we've set up a {@link Ext.data.proxy.Rest Rest Proxy}, which knows how to load and save data to and from a
 * RESTful backend. Let's see how this works:
 *
 *     var user = Ext.create('User', {name: 'Ed Spencer', email: 'ed@sencha.com'});
 *
 *     user.save(); //POST /users
 *
 * Calling {@link #save} on the new Model instance tells the configured RestProxy that we wish to persist this Model's
 * data onto our server. RestProxy figures out that this Model hasn't been saved before because it doesn't have an id,
 * and performs the appropriate action - in this case issuing a POST request to the url we configured (/users). We
 * configure any Proxy on any Model and always follow this API - see {@link Ext.data.proxy.Proxy} for a full list.
 *
 * Loading data via the Proxy is equally easy:
 *
 *     //get a reference to the User model class
 *     var User = Ext.ModelManager.getModel('User');
 *
 *     //Uses the configured RestProxy to make a GET request to /users/123
 *     User.load(123, {
 *         success: function(user) {
 *             console.log(user.getId()); //logs 123
 *         }
 *     });
 *
 * Models can also be updated and destroyed easily:
 *
 *     //the user Model we loaded in the last snippet:
 *     user.set('name', 'Edward Spencer');
 *
 *     //tells the Proxy to save the Model. In this case it will perform a PUT request to /users/123 as this Model already has an id
 *     user.save({
 *         success: function() {
 *             console.log('The User was updated');
 *         }
 *     });
 *
 *     //tells the Proxy to destroy the Model. Performs a DELETE request to /users/123
 *     user.erase({
 *         success: function() {
 *             console.log('The User was destroyed!');
 *         }
 *     });
 *
 * # Usage in Stores
 *
 * It is very common to want to load a set of Model instances to be displayed and manipulated in the UI. We do this by
 * creating a {@link Ext.data.Store Store}:
 *
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'User'
 *     });
 *
 *     //uses the Proxy we set up on Model to load the Store data
 *     store.load();
 *
 * A Store is just a collection of Model instances - usually loaded from a server somewhere. Store can also maintain a
 * set of added, updated and removed Model instances to be synchronized with the server via the Proxy. See the {@link
 * Ext.data.Store Store docs} for more information on Stores.

/**
 * @author Ed Spencer
 *
 * The Store class encapsulates a client side cache of {@link Ext.data.Model Model} objects. Stores load
 * data via a {@link Ext.data.proxy.Proxy Proxy}, and also provide functions for {@link #sort sorting},
 * {@link #filter filtering} and querying the {@link Ext.data.Model model} instances contained within it.
 *
 * Creating a Store is easy - we just tell it the Model and the Proxy to use to load and save its data:
 *
 *     // Set up a {@link Ext.data.Model model} to use in our Store
 *     Ext.define("User", {
 *         extend: "Ext.data.Model",
 *         config: {
 *             fields: [
 *                 {name: "firstName", type: "string"},
 *                 {name: "lastName",  type: "string"},
 *                 {name: "age",       type: "int"},
 *                 {name: "eyeColor",  type: "string"}
 *             ]
 *         }
 *     });
 *
 *     var myStore = Ext.create("Ext.data.Store", {
 *         model: "User",
 *         proxy: {
 *             type: "ajax",
 *             url : "/users.json",
 *             reader: {
 *                 type: "json",
 *                 rootProperty: "users"
 *             }
 *         },
 *         autoLoad: true
 *     });
 *
 *     Ext.create("Ext.List", {
 *         fullscreen: true,
 *         store: myStore,
 *         itemTpl: "{lastName}, {firstName} ({age})"
 *     });
 *
 * In the example above we configured an AJAX proxy to load data from the url '/users.json'. We told our Proxy
 * to use a {@link Ext.data.reader.Json JsonReader} to parse the response from the server into Model object -
 * {@link Ext.data.reader.Json see the docs on JsonReader} for details.
 *
 * The external data file, _/users.json_, is as follows:
 *
 *     {
 *         "success": true,
 *         "users": [
 *             {
 *                 "firstName": "Tommy",
 *                 "lastName": "Maintz",
 *                 "age": 24,
 *                 "eyeColor": "green"
 *             },
 *             {
 *                 "firstName": "Aaron",
 *                 "lastName": "Conran",
 *                 "age": 26,
 *                 "eyeColor": "blue"
 *             },
 *             {
 *                 "firstName": "Jamie",
 *                 "lastName": "Avins",
 *                 "age": 37,
 *                 "eyeColor": "brown"
 *             }
 *         ]
 *     }
 *
 * ## Inline data
 *
 * Stores can also load data inline. Internally, Store converts each of the objects we pass in as {@link #cfg-data}
 * into Model instances:
 *
 *     @example
 *     // Set up a model to use in our Store
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 {name: 'firstName', type: 'string'},
 *                 {name: 'lastName',  type: 'string'},
 *                 {name: 'age',       type: 'int'},
 *                 {name: 'eyeColor',  type: 'string'}
 *             ]
 *         }
 *     });
 *
 *     Ext.create("Ext.data.Store", {
 *         storeId: "usersStore",
 *         model: "User",
 *         data : [
 *             {firstName: "Ed",    lastName: "Spencer"},
 *             {firstName: "Tommy", lastName: "Maintz"},
 *             {firstName: "Aaron", lastName: "Conran"},
 *             {firstName: "Jamie", lastName: "Avins"}
 *         ]
 *     });
 *
 *     Ext.create("Ext.List", {
 *         fullscreen: true,
 *         store: "usersStore",
 *         itemTpl: "{lastName}, {firstName}"
 *     });
 *
 * Loading inline data using the method above is great if the data is in the correct format already (e.g. it doesn't need
 * to be processed by a {@link Ext.data.reader.Reader reader}). If your inline data requires processing to decode the data structure,
 * use a {@link Ext.data.proxy.Memory MemoryProxy} instead (see the {@link Ext.data.proxy.Memory MemoryProxy} docs for an example).
 *
 * Additional data can also be loaded locally using {@link #method-add}.
 *
 * ## Loading Nested Data
 *
 * Applications often need to load sets of associated data - for example a CRM system might load a User and her Orders.
 * Instead of issuing an AJAX request for the User and a series of additional AJAX requests for each Order, we can load a nested dataset
 * and allow the Reader to automatically populate the associated models. Below is a brief example, see the {@link Ext.data.reader.Reader} intro
 * documentation for a full explanation:
 *
 *     // Set up a model to use in our Store
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {

 *
 * ## Filtering and Sorting
 *
 * Stores can be sorted and filtered - in both cases either remotely or locally. The {@link #sorters} and {@link #filters} are
 * held inside {@link Ext.util.MixedCollection MixedCollection} instances to make them easy to manage. Usually it is sufficient to
 * either just specify sorters and filters in the Store configuration or call {@link #sort} or {@link #filter}:
 *
 *     // Set up a model to use in our Store
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: [
 *                 {name: 'firstName', type: 'string'},
 *                 {name: 'lastName', type: 'string'},
 *                 {name: 'age',   type: 'int'}
 *             ]
 *         }
 *     });
 *
 *     var store = Ext.create("Ext.data.Store", {
 *         autoLoad: true,
 *         model: "User",
 *         proxy: {
 *             type: "ajax",
 *             url : "users.json",
 *             reader: {
 *                 type: "json",
 *                 rootProperty: "users"
 *             }
 *         },
 *         sorters: [
 *             {
 *                 property : "age",
 *                 direction: "DESC"
 *             },
 *             {
 *                 property : "firstName",
 *                 direction: "ASC"
 *             }
 *         ],
 *         filters: [
 *             {
 *                 property: "firstName",
 *                 value: /Jamie/
 *             }
 *         ]
 *     });
 *
 *     Ext.create("Ext.List", {
 *         fullscreen: true,
 *         store: store,
 *         itemTpl: "{lastName}, {firstName} ({age})"
 *     });
 *
 * And the data file, _users.json_, is as follows:
 *
 *     {
 *         "success": true,
 *         "users": [
 *             {
 *                 "firstName": "Tommy",
 *                 "lastName": "Maintz",
 *                 "age": 24
 *             },
 *             {
 *                 "firstName": "Aaron",
 *                 "lastName": "Conran",
 *                 "age": 26
 *             },
 *             {
 *                 "firstName": "Jamie",
 *                 "lastName": "Avins",
 *                 "age": 37
 *             }
 *         ]
 *     }
 *
 * The new Store will keep the configured sorters and filters in the MixedCollection instances mentioned above. By default, sorting
 * and filtering are both performed locally by the Store - see {@link #remoteSort} and {@link #remoteFilter} to allow the server to
 * perform these operations instead.
 *
 * Filtering and sorting after the Store has been instantiated is also easy. Calling {@link #filter} adds another filter to the Store
 * and automatically filters the dataset (calling {@link #filter} with no arguments simply re-applies all existing filters). Note that by
 * default your sorters are automatically reapplied if using local sorting.
 *
 *     store.filter('eyeColor', 'Brown');
 *
 * Change the sorting at any time by calling {@link #sort}:
 *
 *     store.sort('height', 'ASC');
 *
 * Note that all existing sorters will be removed in favor of the new sorter data (if {@link #sort} is called with no arguments,
 * the existing sorters are just reapplied instead of being removed). To keep existing sorters and add new ones, just add them
 * to the MixedCollection:
 *
 *     store.sorters.add(new Ext.util.Sorter({
 *         property : 'shoeSize',
 *         direction: 'ASC'
 *     }));
 *
 *     store.sort();
 *
 * ## Registering with StoreManager
 *
 * Any Store that is instantiated with a {@link #storeId} will automatically be registered with the {@link Ext.data.StoreManager StoreManager}.
 * This makes it easy to reuse the same store in multiple views:
 *
 *     // this store can be used several times
 *     Ext.create('Ext.data.Store', {
 *         model: 'User',
 *         storeId: 'usersStore'
 *     });
 *
 *     Ext.create('Ext.List', {
 *         store: 'usersStore'
 *         // other config goes here
 *     });
 *
 *     Ext.create('Ext.view.View', {
 *         store: 'usersStore'
 *         // other config goes here
 *     });
 *
 * ## Further Reading
 *
 * Stores are backed up by an ecosystem of classes that enables their operation. To gain a full understanding of these
 * pieces and how they fit together, see:
 *
 *  - {@link Ext.data.proxy.Proxy Proxy} - overview of what Proxies are and how they are used
 *  - {@link Ext.data.Model Model} - the core class in the data package
 *  - {@link Ext.data.reader.Reader Reader} - used by any subclass of {@link Ext.data.proxy.Server ServerProxy} to read a response

         * To use buffered Stores, initiate the process by loading the first page. The number of rows rendered are
         * determined automatically, and the range of pages needed to keep the cache primed for scrolling is
         * requested and cached.
         * Example:
         *
         *     myStore.loadPage(1); // Load page 1
         *
         * A {@link Ext.grid.plugin.BufferedRenderer BufferedRenderer} is instantiated which will monitor the scrolling in the grid, and
         * refresh the view's rows from the page cache as needed. It will also pull new data into the page
         * cache when scrolling of the view draws upon data near either end of the prefetched data.
         *
         * The margins which trigger view refreshing from the prefetched data are {@link Ext.grid.plugin.BufferedRenderer#numFromEdge},
         * {@link Ext.grid.plugin.BufferedRenderer#leadingBufferZone} and {@link Ext.grid.plugin.BufferedRenderer#trailingBufferZone}.
         *
         * The margins which trigger loading more data into the page cache are, {@link #leadingBufferZone} and
         * {@link #trailingBufferZone}.
         *
         * By default, only 5 pages of data are cached in the page cache, with pages "scrolling" out of the buffer
         * as the view moves down through the dataset.
         * Setting this value to zero means that no pages are *ever* scrolled out of the page cache, and
         * that eventually the whole dataset may become present in the page cache. This is sometimes desirable
         * as long as datasets do not reach astronomical proportions.
         *
         * Selection state may be maintained across page boundaries by configuring the SelectionModel not to discard
         * records from its collection when those Records cycle out of the Store's primary collection. This is done
         * by configuring the SelectionModel like this:
         *
         *     selModel: {
         *         pruneRemoved: false

     *     store.sort('myField', 'DESC');
     *
     * because Store handles the toggling automatically.
     *
     * If the {@link #remoteSort} configuration has been set to `true`, you will have to manually call the {@link #method-load}
     * method after you sort to retrieve the sorted data from the server.

 *
 * Small helper class to make creating {@link Ext.data.Store}s from Array data easier. An ArrayStore will be
 * automatically configured with a {@link Ext.data.reader.Array}.
 *
 * A store configuration would be something like:
 *
 *     var store = Ext.create('Ext.data.ArrayStore', {
 *         // store configs
 *         autoDestroy: true,
 *         storeId: 'myStore',
 *         // reader configs
 *         idIndex: 0,
 *         fields: [
 *            'company',
 *            {name: 'price', type: 'float'},
 *            {name: 'change', type: 'float'},
 *            {name: 'pctChange', type: 'float'},
 *            {name: 'lastChange', type: 'date', dateFormat: 'n/j h:ia'}
 *         ]
 *     });
 *
 * This store is configured to consume a returned object of the form:
 *
 *     var myData = [
 *         ['3m Co',71.72,0.02,0.03,'9/1 12:00am'],
 *         ['Alcoa Inc',29.01,0.42,1.47,'9/1 12:00am'],
 *         ['Boeing Co.',75.43,0.53,0.71,'9/1 12:00am'],
 *         ['Hewlett-Packard Co.',36.53,-0.03,-0.08,'9/1 12:00am'],
 *         ['Wal-Mart Stores, Inc.',45.45,0.73,1.63,'9/1 12:00am']
 *     ];
 *
 * An object literal of this form could also be used as the {@link #data} config option.
 *
 * **Note:** Although not listed here, this class accepts all of the configuration options of
 * **{@link Ext.data.reader.Array ArrayReader}**.

/**
 * Ext.Direct aims to streamline communication between the client and server by providing a single interface that
 * reduces the amount of common code typically required to validate data and handle returned data packets (reading data,
 * error conditions, etc).
 *
 * The Ext.direct namespace includes several classes for a closer integration with the server-side. The Ext.data
 * namespace also includes classes for working with Ext.data.Stores which are backed by data from an Ext.Direct method.
 *
 * # Specification
 *
 * For additional information consult the [Ext.Direct Specification](http://sencha.com/products/extjs/extdirect).
 *
 * # Providers
 *
 * Ext.Direct uses a provider architecture, where one or more providers are used to transport data to and from the
 * server. There are several providers that exist in the core at the moment:
 *
 * - {@link Ext.direct.JsonProvider JsonProvider} for simple JSON operations
 * - {@link Ext.direct.PollingProvider PollingProvider} for repeated requests
 * - {@link Ext.direct.RemotingProvider RemotingProvider} exposes server side on the client.
 *
 * A provider does not need to be invoked directly, providers are added via {@link Ext.direct.Manager}.{@link #addProvider}.
 *
 * # Router
 *
 * Ext.Direct utilizes a "router" on the server to direct requests from the client to the appropriate server-side
 * method. Because the Ext.Direct API is completely platform-agnostic, you could completely swap out a Java based server
 * solution and replace it with one that uses C# without changing the client side JavaScript at all.
 *
 * # Server side events
 *
 * Custom events from the server may be handled by the client by adding listeners, for example:
 *
 *     {"type":"event","name":"message","data":"Successfully polled at: 11:19:30 am"}
 *
 *     // add a handler for a 'message' event sent by the server
 *     Ext.direct.Manager.on('message', function(e){
 *         out.append(String.format('<p><i>{0}</i></p>', e.data));
 *         out.el.scrollTo('t', 100000, true);
 *     });

/**
 * This class is used to send requests to the server using {@link Ext.direct.Manager Ext.Direct}. When a
 * request is made, the transport mechanism is handed off to the appropriate
 * {@link Ext.direct.RemotingProvider Provider} to complete the call.
 *
 * # Specifying the function
 *
 * This proxy expects a Direct remoting method to be passed in order to be able to complete requests.
 * This can be done by specifying the {@link #directFn} configuration. This will use the same direct
 * method for all requests. Alternatively, you can provide an {@link #api} configuration. This
 * allows you to specify a different remoting method for each CRUD action.
 *
 * # Parameters
 *
 * This proxy provides options to help configure which parameters will be sent to the server.
 * By specifying the {@link #paramsAsHash} option, it will send an object literal containing each
 * of the passed parameters. The {@link #paramOrder} option can be used to specify the order in which
 * the remoting method parameters are passed.
 *
 * # Example Usage
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['firstName', 'lastName'],
 *             proxy: {
 *                 type: 'direct',
 *                 directFn: MyApp.getUsers,
 *                 paramOrder: 'id' // Tells the proxy to pass the id as the first parameter to the remoting method.
 *             }
 *         }
 *     });
 *     User.load(1);

 * Small helper class to make creating {@link Ext.data.Store}s from JSON data easier.
 * A JsonStore will be automatically configured with a {@link Ext.data.reader.Json}.
 *
 * A store configuration would be something like:
 *
 *     var store = new Ext.data.JsonStore({
 *         // store configs
 *         autoDestroy: true,
 *         storeId: 'myStore',
 *
 *         proxy: {
 *             type: 'ajax',
 *             url: 'get-images.php',
 *             reader: {
 *                 type: 'json',
 *                 root: 'images',
 *                 idProperty: 'name'
 *             }
 *         },
 *
 *         // alternatively, a {@link Ext.data.Model} name can be given (see {@link Ext.data.Store} for an example)
 *         fields: ['name', 'url', {name:'size', type: 'float'}, {name:'lastmod', type:'date'}]
 *     });
 *
 * This store is configured to consume a returned object of the form:
 *
 *     {
 *         images: [
 *             {name: 'Image one', url:'/GetImage.php?id=1', size:46.5, lastmod: new Date(2007, 10, 29)},
 *             {name: 'Image Two', url:'/GetImage.php?id=2', size:43.2, lastmod: new Date(2007, 10, 30)}
 *         ]
 *     }
 *
 * An object literal of this form could also be used as the {@link #data} config option.
 *

 * The TreeStore is a store implementation that allows for nested data.

 * the hierarchical tree structure combined with a store. This class also relays many events from
 * the Tree for convenience.
 *
 * # Using Models
 *
 * If no Model is specified, an implicit model will be created that implements {@link Ext.data.NodeInterface}.
 * The standard Tree fields will also be copied onto the Model for maintaining their state. These fields are listed
 * in the {@link Ext.data.NodeInterface} documentation.
 *
 * # Reading Nested Data
 *
 * For the tree to read nested data, the {@link Ext.data.reader.Reader} must be configured with a root property,
 * so the reader can find nested data for each node. If a root is not specified, it will default to
 * 'children'.

 * This class generates UUID's according to RFC 4122. This class has a default id property.

 * two {@link Ext.data.Model} instances configured like the following share one generator:
 *
 *     Ext.define('MyApp.data.MyModelX', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             identifier: 'uuid'

 *     });
 *
 *     Ext.define('MyApp.data.MyModelY', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             identifier: 'uuid'
 *         }
 *     });
 *
 * This allows all models using this class to share a commonly configured instance.
 *
 * # Using Version 1 ("Sequential") UUID's
 *
 * If a server can provide a proper timestamp and a "cryptographic quality random number"
 * (as described in RFC 4122), the shared instance can be configured as follows:
 *
 *     Ext.data.identifier.Uuid.Global.reconfigure({
 *         version: 1,
 *         clockSeq: clock, // 14 random bits
 *         salt: salt,      // 48 secure random bits (the Node field)
 *         timestamp: ts    // timestamp per Section 4.1.4
 *     });
 *
 *     // or these values can be split into 32-bit chunks:
 *
 *     Ext.data.identifier.Uuid.Global.reconfigure({
 *         version: 1,
 *         clockSeq: clock,
 *         salt: { lo: saltLow32, hi: saltHigh32 },
 *         timestamp: { lo: timestampLow32, hi: timestamptHigh32 }
 *     });
 *
 * This approach improves the generator's uniqueness by providing a valid timestamp and
 * higher quality random data. Version 1 UUID's should not be used unless this information
 * can be provided by a server and care should be taken to avoid caching of this data.
 *
 * See [http://www.ietf.org/rfc/rfc4122.txt](http://www.ietf.org/rfc/rfc4122.txt) for details.

/**
 * @author Ed Spencer
 *
 * The JsonP proxy is useful when you need to load data from a domain other than the one your application is running on. If
 * your application is running on http://domainA.com it cannot use {@link Ext.data.proxy.Ajax Ajax} to load its data
 * from http://domainB.com because cross-domain ajax requests are prohibited by the browser.
 *
 * We can get around this using a JsonP proxy. JsonP proxy injects a `<script>` tag into the DOM whenever an AJAX request
 * would usually be made. Let's say we want to load data from http://domainB.com/users - the script tag that would be
 * injected might look like this:
 *
 *     <script src="http://domainB.com/users?callback=someCallback"></script>
 *
 * When we inject the tag above, the browser makes a request to that url and includes the response as if it was any
 * other type of JavaScript include. By passing a callback in the url above, we're telling domainB's server that we want
 * to be notified when the result comes in and that it should call our callback function with the data it sends back. So
 * long as the server formats the response to look like this, everything will work:
 *
 *     someCallback({
 *         users: [
 *             {
 *                 id: 1,
 *                 name: "Ed Spencer",
 *                 email: "ed@sencha.com"
 *             }
 *         ]
 *     });
 *
 * As soon as the script finishes loading, the 'someCallback' function that we passed in the url is called with the JSON
 * object that the server returned.
 *
 * JsonP proxy takes care of all of this automatically. It formats the url you pass, adding the callback parameter
 * automatically. It even creates a temporary callback function, waits for it to be called and then puts the data into
 * the Proxy making it look just like you loaded it through a normal {@link Ext.data.proxy.Ajax AjaxProxy}. Here's how
 * we might set that up:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['id', 'name', 'email']
 *         }
 *     });
 *
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'User',
 *         proxy: {
 *             type: 'jsonp',
 *             url : 'http://domainB.com/users'
 *         }
 *     });
 *
 *     store.load();
 *
 * That's all we need to do - JsonP proxy takes care of the rest. In this case the Proxy will have injected a script tag
 * like this:
 *
 *     <script src="http://domainB.com/users?callback=callback1"></script>
 *
 * # Customization
 *
 * This script tag can be customized using the {@link #callbackKey} configuration. For example:
 *
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'User',
 *         proxy: {
 *             type: 'jsonp',
 *             url : 'http://domainB.com/users',
 *             callbackKey: 'theCallbackFunction'
 *         }
 *     });
 *
 *     store.load();
 *
 * Would inject a script tag like this:
 *
 *     <script src="http://domainB.com/users?theCallbackFunction=callback1"></script>
 *
 * # Implementing on the server side
 *
 * The remote server side needs to be configured to return data in this format. Here are suggestions for how you might
 * achieve this using Java, PHP and ASP.net:
 *
 * Java:
 *
 *     boolean jsonP = false;
 *     String cb = request.getParameter("callback");
 *     if (cb != null) {
 *         jsonP = true;
 *         response.setContentType("text/javascript");
 *     } else {
 *         response.setContentType("application/x-json");
 *     }
 *     Writer out = response.getWriter();
 *     if (jsonP) {
 *         out.write(cb + "(");
 *     }
 *     out.print(dataBlock.toJsonString());
 *     if (jsonP) {
 *         out.write(");");
 *     }
 *
 * PHP:
 *
 *     $callback = $_REQUEST['callback'];
 *
 *     // Create the output object.
 *     $output = array('a' => 'Apple', 'b' => 'Banana');
 *
 *     //start output
 *     if ($callback) {
 *         header('Content-Type: text/javascript');
 *         echo $callback . '(' . json_encode($output) . ');';
 *     } else {
 *         header('Content-Type: application/x-json');
 *         echo json_encode($output);
 *     }
 *
 * ASP.net:
 *
 *     String jsonString = "{success: true}";
 *     String cb = Request.Params.Get("callback");
 *     String responseString = "";
 *     if (!String.IsNullOrEmpty(cb)) {
 *         responseString = cb + "(" + jsonString + ")";
 *     } else {
 *         responseString = jsonString;
 *     }
 *     Response.Write(responseString);

/**

 *
 * The LocalStorageProxy uses the new HTML5 localStorage API to save {@link Ext.data.Model Model} data locally on the
 * client browser. HTML5 localStorage is a key-value store (e.g. cannot save complex objects like JSON), so
 * LocalStorageProxy automatically serializes and deserializes data when saving and retrieving it.
 *
 * localStorage is extremely useful for saving user-specific information without needing to build server-side
 * infrastructure to support it. Let's imagine we're writing a Twitter search application and want to save the user's
 * searches locally so they can easily perform a saved search again later. We'd start by creating a Search model:
 *
 *     Ext.define('Search', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['id', 'query'],
 *             proxy: {
 *                 type: 'localstorage',
 *                 id  : 'twitter-Searches'
 *             }
 *         }
 *     });
 *
 * Our Search model contains just two fields - id and query - plus a Proxy definition. The only configuration we need to
 * pass to the LocalStorage proxy is an {@link #id}. This is important as it separates the Model data in this Proxy from
 * all others. The localStorage API puts all data into a single shared namespace, so by setting an id we enable
 * LocalStorageProxy to manage the saved Search data.
 *
 * Saving our data into localStorage is easy and would usually be done with a {@link Ext.data.Store Store}:
 *
 *     //our Store automatically picks up the LocalStorageProxy defined on the Search model
 *     var store = Ext.create('Ext.data.Store', {
 *         model: "Search"
 *     });
 *
 *     //loads any existing Search data from localStorage
 *     store.load();
 *
 *     //now add some Searches
 *     store.add({query: 'Sencha Touch'});
 *     store.add({query: 'Ext JS'});
 *
 *     //finally, save our Search data to localStorage
 *     store.sync();
 *
 * The LocalStorageProxy automatically gives our new Searches an id when we call store.sync(). It encodes the Model data
 * and places it into localStorage. We can also save directly to localStorage, bypassing the Store altogether:
 *
 *     var search = Ext.create('Search', {query: 'Sencha Animator'});
 *
 *     //uses the configured LocalStorageProxy to save the new Search to localStorage
 *     search.save();
 *
 * # Limitations
 *
 * If this proxy is used in a browser where local storage is not supported, the constructor will throw an error. A local
 * storage proxy requires a unique ID which is used as a key in which all record data are stored in the local storage
 * object.
 *
 * It's important to supply this unique ID as it cannot be reliably determined otherwise. If no id is provided but the
 * attached store has a storeId, the storeId will be used. If neither option is presented the proxy will throw an error.

/**

 *
 * The Rest proxy is a specialization of the {@link Ext.data.proxy.Ajax AjaxProxy} which simply maps the four actions
 * (create, read, update and destroy) to RESTful HTTP verbs. For example, let's set up a {@link Ext.data.Model Model}
 * with an inline Rest proxy:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['id', 'name', 'email'],
 *
 *             proxy: {
 *                 type: 'rest',
 *                 url : '/users'
 *             }
 *         }
 *     });
 *
 * Now we can create a new User instance and save it via the Rest proxy. Doing this will cause the Proxy to send a POST
 * request to '/users':
 *
 *     var user = Ext.create('User', {name: 'Ed Spencer', email: 'ed@sencha.com'});
 *
 *     user.save(); //POST /users
 *
 * Let's expand this a little and provide a callback for the {@link Ext.data.Model#save} call to update the Model once
 * it has been created. We'll assume the creation went successfully and that the server gave this user an ID of 123:
 *
 *     user.save({
 *         success: function(user) {
 *             user.set('name', 'Khan Noonien Singh');
 *
 *             user.save(); //PUT /users/123
 *         }
 *     });
 *
 * Now that we're no longer creating a new Model instance, the request method is changed to an HTTP PUT, targeting the
 * relevant url for that user. Now let's delete this user, which will use the DELETE method:
 *
 *         user.erase(); //DELETE /users/123
 *
 * Finally, when we perform a load of a Model or Store, Rest proxy will use the GET method:
 *
 *     //1. Load via Store
 *
 *     //the Store automatically picks up the Proxy from the User model
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'User'
 *     });
 *
 *     store.load(); //GET /users
 *
 *     //2. Load directly from the Model
 *
 *     //GET /users/123
 *     Ext.ModelManager.getModel('User').load(123, {
 *         success: function(user) {
 *             console.log(user.getId()); //outputs 123
 *         }
 *     });
 *
 * # Url generation
 *
 * The Rest proxy is able to automatically generate the urls above based on two configuration options - {@link #appendId} and
 * {@link #format}. If appendId is true (it is by default) then Rest proxy will automatically append the ID of the Model
 * instance in question to the configured url, resulting in the '/users/123' that we saw above.
 *
 * If the request is not for a specific Model instance (e.g. loading a Store), the url is not appended with an id.
 * The Rest proxy will automatically insert a '/' before the ID if one is not already present.
 *
 *     new Ext.data.proxy.Rest({
 *         url: '/users',
 *         appendId: true //default
 *     });
 *
 *     // Collection url: /users
 *     // Instance url  : /users/123
 *
 * The Rest proxy can also optionally append a format string to the end of any generated url:
 *
 *     new Ext.data.proxy.Rest({
 *         url: '/users',
 *         format: 'json'
 *     });
 *
 *     // Collection url: /users.json
 *     // Instance url  : /users/123.json
 *
 * If further customization is needed, simply implement the {@link #buildUrl} method and add your custom generated url
 * onto the {@link Ext.data.Request Request} object that is passed to buildUrl. See [Rest proxy's implementation][1] for
 * an example of how to achieve this.
 *
 * Note that Rest proxy inherits from {@link Ext.data.proxy.Ajax AjaxProxy}, which already injects all of the sorter,
 * filter, group and paging options into the generated url. See the {@link Ext.data.proxy.Ajax AjaxProxy docs} for more
 * details.

/**
 * @author Ed Spencer
 * @class Ext.data.reader.Xml
 * @extends Ext.data.reader.Reader
 *
 * The XML Reader is used by a Proxy to read a server response that is sent back in XML format. This usually
 * happens as a result of loading a Store - for example we might create something like this:
 *
 *     Ext.define('User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['id', 'name', 'email']
 *         }
 *     });
 *
 *     var store = Ext.create('Ext.data.Store', {
 *         model: 'User',
 *         proxy: {
 *             type: 'ajax',
 *             url : 'users.xml',
 *             reader: {
 *                 type: 'xml',
 *                 record: 'user'
 *             }
 *         }
 *     });
 *
 * The example above creates a 'User' model. Models are explained in the {@link Ext.data.Model Model} docs if you're
 * not already familiar with them.
 *
 * We created the simplest type of XML Reader possible by simply telling our {@link Ext.data.Store Store}'s
 * {@link Ext.data.proxy.Proxy Proxy} that we want a XML Reader. The Store automatically passes the configured model to the
 * Store, so it is as if we passed this instead:
 *
 *     reader: {
 *         type : 'xml',
 *         model: 'User',
 *         record: 'user'
 *     }
 *
 * The reader we set up is ready to read data from our server - at the moment it will accept a response like this:
 *
 *     <?xml version="1.0" encoding="UTF-8"?>
 *     <users>
 *          <user>
 *              <id>1</id>
 *              <name>Ed Spencer</name>
 *              <email>ed@sencha.com</email>
 *          </user>
 *          <user>
 *              <id>2</id>
 *              <name>Abe Elias</name>
 *              <email>abe@sencha.com</email>
 *          </user>
 *      </users>
 *
 * The XML Reader uses the configured {@link #record} option to pull out the data for each record - in this case we
 * set record to 'user', so each `<user>` above will be converted into a User model.
 *
 * ## Reading other XML formats
 *
 * If you already have your XML format defined and it doesn't look quite like what we have above, you can usually
 * pass XmlReader a couple of configuration options to make it parse your format. For example, we can use the
 * {@link #rootProperty} configuration to parse data that comes back like this:
 *
 *     <?xml version="1.0" encoding="UTF-8"?>
 *     <users>
 *         <user>
 *             <id>1</id>
 *             <name>Ed Spencer</name>
 *             <email>ed@sencha.com</email>
 *         </user>
 *         <user>
 *             <id>2</id>
 *             <name>Abe Elias</name>
 *             <email>abe@sencha.com</email>
 *         </user>
 *     </users>
 *
 * To parse this we just pass in a {@link #rootProperty} configuration that matches the 'users' above:
 *
 *     reader: {
 *         type: 'xml',
 *         record: 'user',
 *         rootProperty: 'users'
 *     }
 *
 * Note that XmlReader doesn't care whether your {@link #rootProperty} and {@link #record} elements are nested deep
 * inside a larger structure, so a response like this will still work:
 *
 *     <?xml version="1.0" encoding="UTF-8"?>
 *     <deeply>
 *         <nested>
 *             <xml>
 *                 <users>
 *                     <user>
 *                         <id>1</id>
 *                         <name>Ed Spencer</name>
 *                         <email>ed@sencha.com</email>
 *                     </user>
 *                     <user>
 *                         <id>2</id>
 *                         <name>Abe Elias</name>
 *                         <email>abe@sencha.com</email>
 *                     </user>
 *                 </users>
 *             </xml>
 *         </nested>
 *     </deeply>
 *
 * ## Response metadata
 *
 * The server can return additional data in its response, such as the {@link #totalProperty total number of records}
 * and the {@link #successProperty success status of the response}. These are typically included in the XML response
 * like this:
 *
 *     <?xml version="1.0" encoding="UTF-8"?>
 *     <users>
 *         <total>100</total>
 *         <success>true</success>
 *         <user>
 *             <id>1</id>
 *             <name>Ed Spencer</name>
 *             <email>ed@sencha.com</email>
 *         </user>
 *         <user>
 *             <id>2</id>
 *             <name>Abe Elias</name>
 *             <email>abe@sencha.com</email>
 *         </user>
 *     </users>
 *
 * If these properties are present in the XML response they can be parsed out by the XmlReader and used by the
 * Store that loaded it. We can set up the names of these properties by specifying a final pair of configuration
 * options:
 *
 *     reader: {
 *         type: 'xml',
 *         rootProperty: 'users',
 *         totalProperty  : 'total',
 *         successProperty: 'success'
 *     }
 *
 * These final options are not necessary to make the Reader work, but can be useful when the server needs to report
 * an error or if it needs to indicate that there is a lot of data available of which only a subset is currently being
 * returned.
 *
 * ## Response format
 *
 * __Note:__ In order for the browser to parse a returned XML document, the Content-Type header in the HTTP
 * response must be set to "text/xml" or "application/xml". This is very important - the XmlReader will not
 * work correctly otherwise.

/**
 * A ListItem is a container for {@link Ext.dataview.List} with

/**
 * The DelayedTask class provides a convenient way to "buffer" the execution of a method,
 * performing `setTimeout` where a new timeout cancels the old timeout. When called, the
 * task will wait the specified time period before executing. If during that time period,
 * the task is called again, the original call will be canceled. This continues so that
 * the function is only called a single time for each iteration.
 *
 * This method is especially useful for things like detecting whether a user has finished
 * typing in a text field. An example would be performing validation on a keypress. You can
 * use this class to buffer the keypress events for a certain number of milliseconds, and
 * perform only if they stop for that amount of time.
 *
 * Using {@link Ext.util.DelayedTask} is very simple:
 *
 *     //create the delayed task instance with our callback
 *     var task = Ext.create('Ext.util.DelayedTask', {
 *          fn: function() {
 *             console.log('callback!');
 *          }
 *     });
 *
 *     task.delay(1500); //the callback function will now be called after 1500ms
 *
 *     task.cancel(); //the callback function will never be called now, unless we call delay() again
 *
 * ## Example
 *
 *     @example
 *     //create a textfield where we can listen to text
 *     var field = Ext.create('Ext.field.Text', {
 *         xtype: 'textfield',
 *         label: 'Length: 0'
 *     });
 *
 *     //add the textfield into a fieldset
 *     Ext.Viewport.add({
 *         xtype: 'formpanel',
 *         items: [{
 *             xtype: 'fieldset',
 *             items: [field],
 *             instructions: 'Type into the field and watch the count go up after 500ms.'
 *         }]
 *     });
 *
 *     //create our delayed task with a function that returns the fields length as the fields label
 *     var task = Ext.create('Ext.util.DelayedTask', function() {
 *         field.setLabel('Length: ' + field.getValue().length);
 *     });
 *
 *     // Wait 500ms before calling our function. If the user presses another key
 *     // during that 500ms, it will be canceled and we'll wait another 500ms.
 *     field.on('keyup', function() {
 *         task.delay(500);
 *     });
 *
 * @constructor
 * The parameters to this constructor serve as defaults and are not required.
 * @param {Function} fn The default function to call.

 *
 * Just as {@link Ext.dom.Element} wraps around a native DOM node, {@link Ext.event.Event} wraps the browser's native
 * event-object normalizing cross-browser differences such as mechanisms to stop event-propagation along with a method
 * to prevent default actions from taking place.
 *
 * Here is a simple example of how you use it:
 *
 *     @example preview
 *     Ext.Viewport.add({
 *         layout: 'fit',
 *         items: [
 *             {
 *                 docked: 'top',
 *                 xtype: 'toolbar',
 *                 title: 'Ext.event.Event example!'
 *             },
 *             {
 *                 id: 'logger',
 *                 styleHtmlContent: true,
 *                 html: 'Tap somewhere!',
 *                 padding: 5
 *             }
 *         ]
 *     });
 *
 *     Ext.Viewport.element.on({
 *         tap: function(e, node) {
 *             var string = '';
 *
 *             string += 'You tapped at: <strong>{ x: ' + e.pageX + ', y: ' + e.pageY + ' }</strong> <i>(e.pageX & e.pageY)</i>';
 *             string += '<hr />';
 *             string += 'The HTMLElement you tapped has the className of: <strong>' + e.target.className + '</strong> <i>(e.target)</i>';
 *             string += '<hr />';
 *             string += 'The HTMLElement which has the listener has a className of: <strong>' + e.getTarget().className + '</strong> <i>(e.getTarget())</i>';
 *
 *             Ext.getCmp('logger').setHtml(string);
 *         }
 *     });
 *
 * ## Recognizers
 *
 * Sencha Touch includes a bunch of default event recognizers to know when a user taps, swipes, etc.
 *
 * For a full list of default recognizers, and more information, please view the {@link Ext.event.recognizer.Recognizer} documentation.

 * The checkbox field is an enhanced version of the native browser checkbox and is great for enabling your user to
 * choose one or more items from a set (for example choosing toppings for a pizza order). It works like any other
 * {@link Ext.field.Field field} and is usually found in the context of a form:
 *
 * ## Example
 *
 *     @example miniphone preview
 *     var form = Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [

 *                 label: 'Tomato',
 *                 value: 'tomato',
 *                 checked: true
 *             },

 *                 label: 'Salami'
 *             },
 *             {
 *                 xtype: 'toolbar',

 *                 ]
 *             }
 *         ]
 *     });
 *
 *
 * The form above contains two check boxes - one for Tomato, one for Salami. We configured the Tomato checkbox to be
 * checked immediately on load, and the Salami checkbox to be unchecked. We also specified an optional text
 * {@link #value} that will be sent when we submit the form. We can get this value using the Form's
 * {@link Ext.form.Panel#getValues getValues} function, or have it sent as part of the data that is sent when the
 * form is submitted:
 *
 *     form.getValues(); //contains a key called 'tomato' if the Tomato field is still checked
 *     form.submit(); //will send 'tomato' in the form submission data
 *

/**
 * A general picker class. {@link Ext.picker.Slot}s are used to organize multiple scrollable slots into a single picker. {@link #slots} is
 * the only necessary configuration.
 *
 * The {@link #slots} configuration with a few key values:
 *
 * - `name`: The name of the slot (will be the key when using {@link #getValues} in this {@link Ext.picker.Picker}).
 * - `title`: The title of this slot (if {@link #useTitles} is set to `true`).
 * - `data`/`store`: The data or store to use for this slot.
 *
 * Remember, {@link Ext.picker.Slot} class extends from {@link Ext.dataview.DataView}.
 *
 * ## Examples
 *
 *     @example miniphone preview
 *     var picker = Ext.create('Ext.Picker', {
 *         slots: [
 *             {
 *                 name : 'limit_speed',
 *                 title: 'Speed',
 *                 data : [
 *                     {text: '50 KB/s', value: 50},
 *                     {text: '100 KB/s', value: 100},
 *                     {text: '200 KB/s', value: 200},
 *                     {text: '300 KB/s', value: 300}
 *                 ]
 *             }
 *         ]
 *     });
 *     Ext.Viewport.add(picker);
 *     picker.show();
 *
 * You can also customize the top toolbar on the {@link Ext.picker.Picker} by changing the {@link #doneButton} and {@link #cancelButton} configurations:
 *
 *     @example miniphone preview
 *     var picker = Ext.create('Ext.Picker', {
 *         doneButton: 'I\'m done!',
 *         cancelButton: false,
 *         slots: [
 *             {

/**
 * A date picker component which shows a Date Picker on the screen. This class extends from {@link Ext.picker.Picker}
 * and {@link Ext.Sheet} so it is a popup.
 *
 * This component has no required configurations.
 *
 * ## Examples
 *
 *     @example miniphone preview
 *     var datePicker = Ext.create('Ext.picker.Date');
 *     Ext.Viewport.add(datePicker);
 *     datePicker.show();
 *
 * You may want to adjust the {@link #yearFrom} and {@link #yearTo} properties:
 *
 *     @example miniphone preview
 *     var datePicker = Ext.create('Ext.picker.Date', {
 *         yearFrom: 2000,
 *         yearTo  : 2015
 *     });
 *     Ext.Viewport.add(datePicker);
 *     datePicker.show();
 *
 * You can set the value of the {@link Ext.picker.Date} to the current date using `new Date()`:
 *
 *     @example miniphone preview
 *     var datePicker = Ext.create('Ext.picker.Date', {
 *         value: new Date()
 *     });
 *     Ext.Viewport.add(datePicker);
 *     datePicker.show();
 *
 * And you can hide the titles from each of the slots by using the {@link #useTitles} configuration:
 *
 *     @example miniphone preview
 *     var datePicker = Ext.create('Ext.picker.Date', {
 *         useTitles: false
 *     });
 *     Ext.Viewport.add(datePicker);
 *     datePicker.show();

/**
 * This is a specialized field which shows a {@link Ext.picker.Date} when tapped. If it has a predefined value,
 * or a value is selected in the {@link Ext.picker.Date}, it will be displayed like a normal {@link Ext.field.Text}
 * (but not selectable/changable).
 *
 *     Ext.create('Ext.field.DatePicker', {
 *         label: 'Birthday',
 *         value: new Date()
 *     });
 *
 * {@link Ext.field.DatePicker} fields are very simple to implement, and have no required configurations.
 *
 * For more information regarding forms and fields, please review [Using Forms in Sencha Touch Guide](../../../components/forms.html)
 * 
 * ## Examples
 *
 * It can be very useful to set a default {@link #value} configuration on {@link Ext.field.DatePicker} fields. In
 * this example, we set the {@link #value} to be the current date. You can also use the {@link #setValue} method to
 * update the value at any time.
 *
 *     @example miniphone preview
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 items: [
 *                     {
 *                         xtype: 'datepickerfield',
 *                         label: 'Birthday',
 *                         name: 'birthday',
 *                         value: new Date()
 *                     }
 *                 ]
 *             },
 *             {
 *                 xtype: 'toolbar',
 *                 docked: 'bottom',
 *                 items: [
 *                     { xtype: 'spacer' },
 *                     {
 *                         text: 'setValue',
 *                         handler: function() {
 *                             var datePickerField = Ext.ComponentQuery.query('datepickerfield')[0];
 *
 *                             var randomNumber = function(from, to) {
 *                                 return Math.floor(Math.random() * (to - from + 1) + from);
 *                             };
 *
 *                             datePickerField.setValue({
 *                                 month: randomNumber(0, 11),
 *                                 day  : randomNumber(0, 28),
 *                                 year : randomNumber(1980, 2011)
 *                             });
 *                         }
 *                     },
 *                     { xtype: 'spacer' }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * When you need to retrieve the date from the {@link Ext.field.DatePicker}, you can either use the {@link #getValue} or
 * {@link #getFormattedValue} methods:
 *
 *     @example preview
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 items: [
 *                     {
 *                         xtype: 'datepickerfield',
 *                         label: 'Birthday',
 *                         name: 'birthday',
 *                         value: new Date()
 *                     }
 *                 ]
 *             },
 *             {
 *                 xtype: 'toolbar',
 *                 docked: 'bottom',
 *                 items: [
 *                     {
 *                         text: 'getValue',
 *                         handler: function() {
 *                             var datePickerField = Ext.ComponentQuery.query('datepickerfield')[0];
 *                             Ext.Msg.alert(null, datePickerField.getValue());
 *                         }
 *                     },
 *                     { xtype: 'spacer' },
 *                     {
 *                         text: 'getFormattedValue',
 *                         handler: function() {
 *                             var datePickerField = Ext.ComponentQuery.query('datepickerfield')[0];
 *                             Ext.Msg.alert(null, datePickerField.getFormattedValue());
 *                         }
 *                     }

/**
 * The Email field creates an HTML5 email input and is usually created inside a form. Because it creates an HTML email
 * input field, most browsers will show a specialized virtual keyboard for email address input. Aside from that, the
 * email field is just a normal text field. Here's an example of how to use it in a form:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 title: 'Register',
 *                 items: [
 *                     {
 *                         xtype: 'emailfield',
 *                         label: 'Email',
 *                         name: 'email'
 *                     },
 *                     {
 *                         xtype: 'passwordfield',
 *                         label: 'Password',
 *                         name: 'password'
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * Or on its own, outside of a form:
 *
 *     Ext.create('Ext.field.Email', {
 *         label: 'Email address',
 *         value: 'prefilled@email.com'
 *     });
 *
 * Because email field inherits from {@link Ext.field.Text textfield} it gains all of the functionality that text fields
 * provide, including getting and setting the value at runtime, validations and various events that are fired as the
 * user interacts with the component. Check out the {@link Ext.field.Text} docs to see the additional functionality
 * available.

/**
 * Hidden fields allow you to easily inject additional data into a {@link Ext.form.Panel form} without displaying
 * additional fields on the screen. This is often useful for sending dynamic or previously collected data back to the
 * server in the same request as the normal form submission. For example, here is how we might set up a form to send
 * back a hidden userId field:
 *
 *     @example
 *     var form = Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 title: 'Enter your name',
 *                 items: [
 *                     {
 *                         xtype: 'hiddenfield',
 *                         name: 'userId',
 *                         value: 123
 *                     },
 *                     {
 *                         xtype: 'checkboxfield',
 *                         label: 'Enable notifications',
 *                         name: 'notifications'
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * In the form above we created two fields - a hidden field and a {@link Ext.field.Checkbox check box field}. Only the
 * check box will be visible, but both fields will be submitted. Hidden fields cannot be tabbed to - they are removed
 * from the tab index so when your user taps the next/previous field buttons the hidden field is skipped over.
 *
 * It's easy to read and update the value of a hidden field within a form. Using the example above, we can get a
 * reference to the hidden field and then set it to a new value in 2 lines of code:
 *
 *     var userId = form.down('hiddenfield')[0];
 *     userId.setValue(1234);

/**
 * The Number field creates an HTML5 number input and is usually created inside a form. Because it creates an HTML
 * number input field, most browsers will show a specialized virtual keyboard for entering numbers. The Number field
 * only accepts numerical input and also provides additional spinner UI that increases or decreases the current value
 * by a configured {@link #stepValue step value}. Here's how we might use one in a form:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 title: 'How old are you?',
 *                 items: [
 *                     {
 *                         xtype: 'numberfield',
 *                         label: 'Age',
 *                         minValue: 18,
 *                         maxValue: 150,
 *                         name: 'age'
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * Or on its own, outside of a form:
 *
 *     Ext.create('Ext.field.Number', {
 *         label: 'Age',
 *         value: '26'
 *     });
 *
 * ## minValue, maxValue and stepValue
 *
 * The {@link #minValue} and {@link #maxValue} configurations are self-explanatory and simply constrain the value
 * entered to the range specified by the configured min and max values. The other option exposed by this component
 * is {@link #stepValue}, which enables you to set how much the value changes every time the up and down spinners
 * are tapped on. For example, to create a salary field that ticks up and down by $1,000 each tap we can do this:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 title: 'Are you rich yet?',
 *                 items: [
 *                     {
 *                         xtype: 'numberfield',
 *                         label: 'Salary',
 *                         value: 30000,
 *                         minValue: 25000,
 *                         maxValue: 50000,
 *                         stepValue: 1000
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * This creates a field that starts with a value of $30,000, steps up and down in $1,000 increments and will not go
 * beneath $25,000 or above $50,000.
 *
 * Because number field inherits from {@link Ext.field.Text textfield} it gains all of the functionality that text
 * fields provide, including getting and setting the value at runtime, validations and various events that are fired as
 * the user interacts with the component. Check out the {@link Ext.field.Text} docs to see the additional functionality

/**

 *         fullscreen: true,
 *         items: [
 *             {

 *                 name : 'color',
 *                 value: 'red',
 *                 label: 'Red',
 *                 checked: true
 *             },
 *             {
 *                 xtype: 'radiofield',
 *                 name : 'color',

 *                 label: 'Blue'
 *             }
 *         ]
 *     });
 *
 * Above we created a simple form which allows the user to pick a color from the options red, green and blue. Because
 * we gave each of the fields above the same {@link #name}, the radio field ensures that only one of them can be
 * checked at a time. When we come to get the values out of the form again or submit it to the server, only 1 value
 * will be sent for each group of radio fields with the same name:
 *
 *     form.getValues(); //looks like {color: 'red'}
 *     form.submit(); //sends a single field back to the server (in this case color: red)

/**
 * The Search field creates an HTML5 search input and is usually created inside a form. Because it creates an HTML
 * search input type, the visual styling of this input is slightly different to normal text input controls (the corners
 * are rounded), though the virtual keyboard displayed by the operating system is the standard keyboard control.
 *
 * As with all other form fields in Sencha Touch, the search field gains a "clear" button that appears whenever there
 * is text entered into the form, and which removes that text when tapped.
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 title: 'Search',
 *                 items: [
 *                     {
 *                         xtype: 'searchfield',
 *                         label: 'Query',
 *                         name: 'query'
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * Or on its own, outside of a form:
 *
 *     Ext.create('Ext.field.Search', {
 *         label: 'Search:',
 *         value: 'query'
 *     });
 *
 * Because search field inherits from {@link Ext.field.Text textfield} it gains all of the functionality that text
 * fields provide, including getting and setting the value at runtime, validations and various events that are fired
 * as the user interacts with the component. Check out the {@link Ext.field.Text} docs to see the additional
 * functionality available.

/**
 * The slider is a way to allow the user to select a value from a given numerical range. You might use it for choosing
 * a percentage, combine two of them to get min and max values, or use three of them to specify the hex values for a
 * color. Each slider contains a single 'thumb' that can be dragged along the slider's length to change the value.
 * Sliders are equally useful inside {@link Ext.form.Panel forms} and standalone. Here's how to quickly create a
 * slider in form, in this case enabling a user to choose a percentage:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'sliderfield',
 *                 label: 'Percentage',
 *                 value: 50,
 *                 minValue: 0,
 *                 maxValue: 100
 *             }
 *         ]
 *     });
 *
 * In this case we set a starting value of 50%, and defined the min and max values to be 0 and 100 respectively, giving
 * us a percentage slider. Because this is such a common use case, the defaults for {@link #minValue} and
 * {@link #maxValue} are already set to 0 and 100 so in the example above they could be removed.
 *
 * It's often useful to render sliders outside the context of a form panel too. In this example we create a slider that
 * allows a user to choose the waist measurement of a pair of jeans. Let's say the online store we're making this for
 * sells jeans with waist sizes from 24 inches to 60 inches in 2 inch increments - here's how we might achieve that:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'sliderfield',
 *                 label: 'Waist Measurement',
 *                 minValue: 24,
 *                 maxValue: 60,
 *                 increment: 2,
 *                 value: 32
 *             }
 *         ]
 *     });
 *
 * Now that we've got our slider, we can ask it what value it currently has and listen to events that it fires. For
 * example, if we wanted our app to show different images for different sizes, we can listen to the {@link #change}
 * event to be informed whenever the slider is moved:
 *
 *     slider.on('change', function(field, newValue) {
 *         if (newValue[0] > 40) {
 *             imgComponent.setSrc('large.png');
 *         } else {
 *             imgComponent.setSrc('small.png');
 *         }
 *     }, this);
 *
 * Here we listened to the {@link #change} event on the slider and updated the background image of an
 * {@link Ext.Img image component} based on what size the user selected. Of course, you can use any logic inside your
 * event listener.
 *

/**
 * The urlfield creates an HTML5 url input and is usually created inside a form. Because it creates an HTML url input
 * field, most browsers will show a specialized virtual keyboard for web address input. Aside from that, the urlfield
 * is just a normal text field. Here's an example of how to use it in a form:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 title: 'Add Bookmark',
 *                 items: [
 *                     {
 *                         xtype: 'urlfield',
 *                         label: 'Url',
 *                         name: 'url'
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * Or on its own, outside of a form:
 *
 *     Ext.create('Ext.field.Url', {
 *         label: 'Web address',
 *         value: 'http://sencha.com'
 *     });
 *
 * Because url field inherits from {@link Ext.field.Text textfield} it gains all of the functionality that text fields
 * provide, including getting and setting the value at runtime, validations and various events that are fired as the
 * user interacts with the component. Check out the {@link Ext.field.Text} docs to see the additional functionality
 * available.
 *

/**
 * A FieldSet is a great way to visually separate elements of a form. It's normally used when you have a form with
 * fields that can be divided into groups - for example a customer's billing details in one fieldset and their shipping
 * address in another. A fieldset can be used inside a form or on its own elsewhere in your app. Fieldsets can
 * optionally have a title at the top and instructions at the bottom. Here's how we might create a FieldSet inside a
 * form:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'fieldset',
 *                 title: 'About You',
 *                 instructions: 'Tell us all about yourself',
 *                 items: [
 *                     {
 *                         xtype: 'textfield',
 *                         name : 'firstName',
 *                         label: 'First Name'
 *                     },
 *                     {
 *                         xtype: 'textfield',
 *                         name : 'lastName',
 *                         label: 'Last Name'
 *                     }
 *                 ]
 *             }
 *         ]
 *     });
 *
 * Above we created a {@link Ext.form.Panel form} with a fieldset that contains two text fields. In this case, all
 * of the form fields are in the same fieldset, but for longer forms we may choose to use multiple fieldsets. We also
 * configured a {@link #title} and {@link #instructions} to give the user more information on filling out the form if
 * required.

/**
 * The Form panel presents a set of form fields and provides convenient ways to load and save data. Usually a form
 * panel just contains the set of fields you want to display, ordered inside the items configuration like this:
 *
 *     @example
 *     var form = Ext.create('Ext.form.Panel', {
 *         fullscreen: true,
 *         items: [
 *             {
 *                 xtype: 'textfield',
 *                 name: 'name',
 *                 label: 'Name'
 *             },
 *             {
 *                 xtype: 'emailfield',
 *                 name: 'email',
 *                 label: 'Email'
 *             },
 *             {
 *                 xtype: 'passwordfield',
 *                 name: 'password',
 *                 label: 'Password'
 *             }
 *         ]
 *     });
 *
 * Here we just created a simple form panel which could be used as a registration form to sign up to your service. We
 * added a plain {@link Ext.field.Text text field} for the user's Name, an {@link Ext.field.Email email field} and
 * finally a {@link Ext.field.Password password field}. In each case we provided a {@link Ext.field.Field#name name}
 * config on the field so that we can identify it later on when we load and save data on the form.
 *
 * ##Loading data
 *
 * Using the form we created above, we can load data into it in a few different ways, the easiest is to use
 * {@link #setValues}:
 *
 *     form.setValues({
 *         name: 'Ed',
 *         email: 'ed@sencha.com',
 *         password: 'secret'
 *     });
 *
 * It's also easy to load {@link Ext.data.Model Model} instances into a form - let's say we have a User model and want
 * to load a particular instance into our form:
 *
 *     Ext.define('MyApp.model.User', {
 *         extend: 'Ext.data.Model',
 *         config: {
 *             fields: ['name', 'email', 'password']
 *         }
 *     });
 *
 *     var ed = Ext.create('MyApp.model.User', {
 *         name: 'Ed',
 *         email: 'ed@sencha.com',
 *         password: 'secret'
 *     });
 *
 *     form.setRecord(ed);
 *
 * ##Retrieving form data
 *
 * Getting data out of the form panel is simple and is usually achieve via the {@link #getValues} method:
 *
 *     var values = form.getValues();
 *
 *     //values now looks like this:
 *     {
 *         name: 'Ed',
 *         email: 'ed@sencha.com',
 *         password: 'secret'
 *     }
 *
 * It's also possible to listen to the change events on individual fields to get more timely notification of changes
 * that the user is making. Here we expand on the example above with the User model, updating the model as soon as
 * any of the fields are changed:
 *
 *     var form = Ext.create('Ext.form.Panel', {
 *         listeners: {
 *             '> field': {
 *                 change: function(field, newValue, oldValue) {
 *                     ed.set(field.getName(), newValue);
 *                 }
 *             }
 *         },
 *         items: [
 *             {
 *                 xtype: 'textfield',
 *                 name: 'name',
 *                 label: 'Name'
 *             },
 *             {
 *                 xtype: 'emailfield',
 *                 name: 'email',
 *                 label: 'Email'
 *             },
 *             {
 *                 xtype: 'passwordfield',
 *                 name: 'password',
 *                 label: 'Password'
 *             }
 *         ]
 *     });
 *
 * The above used a new capability of Sencha Touch 2.0, which enables you to specify listeners on child components of any
 * container. In this case, we attached a listener to the {@link Ext.field.Text#change change} event of each form
 * field that is a direct child of the form panel. Our listener gets the name of the field that fired the change event,
 * and updates our {@link Ext.data.Model Model} instance with the new value. For example, changing the email field
 * in the form will update the Model's email field.
 *
 * ##Submitting forms
 *
 * There are a few ways to submit form data. In our example above we have a Model instance that we have updated, giving
 * us the option to use the Model's {@link Ext.data.Model#save save} method to persist the changes back to our server,
 * without using a traditional form submission. Alternatively, we can send a normal browser form submit using the
 * {@link #method} method:
 *
 *     form.submit({

 * @author Robert Dougan <rob@sencha.com>
 *
 * NavigationView is basically a {@link Ext.Container} with a {@link Ext.layout.Card card} layout, so only one view
 * can be visible at a time. However, NavigationView also adds extra functionality on top of this to allow
 * you to `push` and `pop` views at any time. When you do this, your NavigationView will automatically animate
 * between your current active view, and the new view you want to `push`, or the previous view you want to `pop`.
 *
 * Using the NavigationView is very simple. Here is a basic example of it in action:
 *
 *     @example
 *     var view = Ext.create('Ext.NavigationView', {
 *         fullscreen: true,
 *
 *         items: [{
 *             title: 'First',
 *             items: [{
 *                 xtype: 'button',
 *                 text: 'Push a new view!',
 *                 handler: function() {
 *                     // use the push() method to push another view. It works much like
 *                     // add() or setActiveItem(). it accepts a view instance, or you can give it
 *                     // a view config.
 *                     view.push({
 *                         title: 'Second',
 *                         html: 'Second view!'
 *                     });
 *                 }
 *             }]
 *         }]
 *     });
 *
 * Now, here comes the fun part: you can push any view/item into the NavigationView, at any time, and it will
 * automatically handle the animations between the two views, including adding a back button (if necessary)
 * and showing the new title.
 *
 *     view.push({
 *         title: 'A new view',
 *         html: 'Some new content'
 *     });
 *
 * As you can see, it is as simple as calling the {@link #method-push} method, with a new view (instance or object). Done.
 *
 * You can also `pop` a view at any time. This will remove the top-most view from the NavigationView, and animate back
 * to the previous view. You can do this using the {@link #method-pop} method (which requires no arguments).
 *
 *     view.pop();
 *
 *  Applications that need compatibility with ##Older Android## devices will want to see the {@link #layout} config for details on
 *  disabling navigation view animations as these devices have poor animation support and performance.

/**
 * @class Ext.plugin.SortableList
 * @extends Ext.Component
 * The SortableList plugin gives your list items the ability to be reordered by tapping and 
 * dragging elements within the item.   
 *
 * The list-sortablehandle is not added to your tpl by default, so it's important that you 
 * manually include it. It's also important to recognize that list-items are not draggable 
 * themselves.  You must add an element to the itemTpl for it to be dragged.
 *
 *     Ext.Viewport.add({
 *          xtype: 'list',
 *          infinite: true,
 *          plugins: 'sortablelist',
 *          itemTpl: '<span class="myStyle ' + Ext.baseCSSPrefix + 'list-sortablehandle"></span>{text}',
 *          data: [{
 *              text: 'Item 1'
 *          }, {
 *              text: 'Item 2'
 *          }, {
 *              text: 'Item 3'
 *          }]
 *     });
 *
 * The CSS for MyStyle can be anything that creates an element to tap and drag.  For this 
 * example we made a simple rectangle like so:
 *
 *      .myStyle{
 *          width:30px;
 *          height:20px;
 *          background:gray;
 *          float:left;
 *      }
 * 
 * Note: You must have infinite set to 'true' when using the SortableList plugin.

/**
 * Tab Panels are a great way to allow the user to switch between several pages that are all full screen. Each
 * Component in the Tab Panel gets its own Tab, which shows the Component when tapped on. Tabs can be positioned at
 * the top or the bottom of the Tab Panel, and can optionally accept title and icon configurations.
 *
 * Here's how we can set up a simple Tab Panel with tabs at the bottom. Use the controls at the top left of the example
 * to toggle between code mode and live preview mode (you can also edit the code and see your changes in the live
 * preview):
 *
 *     @example miniphone preview
 *     Ext.create('Ext.TabPanel', {
 *         fullscreen: true,
 *         tabBarPosition: 'bottom',
 *
 *         defaults: {
 *             styleHtmlContent: true
 *         },
 *
 *         items: [
 *             {
 *                 title: 'Home',
 *                 iconCls: 'home',
 *                 html: 'Home Screen'
 *             },
 *             {
 *                 title: 'Contact',
 *                 iconCls: 'user',
 *                 html: 'Contact Screen'
 *             }
 *         ]
 *     });
 * One tab was created for each of the {@link Ext.Panel panels} defined in the items array. Each tab automatically uses
 * the title and icon defined on the item configuration, and switches to that item when tapped on. We can also position
 * the tab bar at the top, which makes our Tab Panel look like this:
 *
 *     @example miniphone preview
 *     Ext.create('Ext.TabPanel', {
 *         fullscreen: true,
 *
 *         defaults: {
 *             styleHtmlContent: true
 *         },
 *
 *         items: [
 *             {
 *                 title: 'Home',
 *                 html: 'Home Screen'
 *             },
 *             {
 *                 title: 'Contact',
 *                 html: 'Contact Screen'
 *             }
 *         ]
 *     });

         * - **type** - string, optional - The type of the gradient. Available types are: 'linear', 'radial'. Defaults to 'linear'.

    // When the data set from the store changes, series.processData() is called, which does its thing
    // at the series level and then calls series.updateLabelData() to update the labels in the sprites
    // that belong to the series. At the same time, series.processData() calls axis.processData(), which
    // also does its thing but at the axis level, and also needs to update the labels for the sprite(s)
    // that belong to the axis. This is not that simple, however. So how are the axis labels rendered?
    // First, axis.sprite.Axis.render() calls renderLabels() which obtains the majorTicks from the 
    // axis.layout and iterate() through them. The majorTicks are an object returned by snapEnds() below
    // which provides a getLabel() function that returns the label from the axis.layoutContext.data array.
    // So now the question is: how are the labels transferred from the axis.layout to the axis.layoutContext?
    // The easy response is: it's in calculateLayout() below. The issue is to call calculateLayout() because
    // it takes in an axis.layoutContext that can only be created in axis.sprite.Axis.doLayout(), which is 
    // a private "updater" function that is called by all the sprite's "dirtyTriggers". Of course, we don't 
    // want to call doLayout() directly from here, so instead we update the sprite's data attribute, which 
    // sets the dirtyTrigger which calls doLayout() which calls calculateLayout() etc...
    // Note that the sprite's data attribute could be set to any value and it would still result in the  
    // dirtyTrigger we need. For consistency, however, it is set to the labels.

     * @cfg {Function} renderer
     * A function that can be provided to set custom styling properties to each rendered element.
     * It receives `(sprite, config, rendererData, index)` as parameters.
     *
     * @param {Object} sprite The sprite affected by the renderer. The visual attributes are in `sprite.attr`.
     * The data field is available in `sprite.getField()`.
     * @param {Object} config The sprite configuration. It varies with the series and the type of sprite:
     * for instance, a Line chart sprite might have just the `x` and `y` properties while a Bar
     * chart sprite also has `width` and `height`. A `type` might be present too. For instance to
     * draw each marker and each segment of a Line chart, the renderer is called with the
     * `config.type` set to either `marker` or `line`.
     * @param {Object} rendererData A record with different properties depending on the type of chart.
     * The only guaranteed property is `rendererData.store`, the store used by the series.
     * In some cases, a store may not exist: for instance a Gauge chart may read its value directly
     * from its configuration; in this case rendererData.store is null and the value is
     * available in rendererData.value.
     * @param {Number} index The index of the sprite. It is usually the index of the store record associated
     * with the sprite, in which case the record can be obtained with `store.getData().items[index]`.
     * If the chart is not associated with a store, the index represents the index of the sprite within
     * the series. For instance a Gauge chart may have as many sprites as there are sectors in the
     * background of the gauge, plus one for the needle.
     *
     * @return {Object} The attributes that have been changed or added. Note: it is usually possible to
     * add or modify the attributes directly into the `config` parameter and not return anything,
     * but returning an object with only those attributes that have been changed may allow for
     * optimizations in the rendering of some series. Example to draw every other item in red:
     *
     *      renderer: function (sprite, config, rendererData, index) {
     *          if (index % 2 == 0) {
     *              return { strokeStyle: 'red' };
