/**
 * Controllers are the glue that binds an application together. All they really do is listen for events (usually from
 * views) and take some action. Here's how we might create a Controller to manage Users:
 *
 *      Ext.define('MyApp.controller.Users', {
 *          extend: 'Ext.app.Controller',
 *
 *          init: function() {
 *              console.log('Initialized Users! This happens before ' +
 *                          'the Application launch() function is called');
 *          }
 *      });
 *
 * The init function is a special method that is called when your application boots. It is called before the
 * {@link Ext.app.Application Application}'s launch function is executed so gives a hook point to run any code before
 * your Viewport is created.
 *
 * The init function is a great place to set up how your controller interacts with the view, and is usually used in
 * conjunction with another Controller function - {@link Ext.app.Controller#control control}. The control function
 * makes it easy to listen to events on your view classes and take some action with a handler function. Let's update
 * our Users controller to tell us when the panel is rendered:
 *
 *      Ext.define('MyApp.controller.Users', {
 *          extend: 'Ext.app.Controller',
 *
 *          init: function() {
 *              this.control({
 *                  'viewport > panel': {
 *                      render: this.onPanelRendered
 *                  }
 *              });
 *          },
 *
 *          onPanelRendered: function() {
 *              console.log('The panel was rendered');
 *          }
 *      });
 *
 * We've updated the init function to use {@link Ext.app.Controller#control control method} to set up listeners on views
 * in our application. The control method uses the ComponentQuery engine to quickly and easily get references to components
 * on the page. If you are not familiar with ComponentQuery yet, be sure to check out the
 * {@link Ext.ComponentQuery documentation}. In brief though, it allows us to pass a CSS-like selector that will find
 * every matching component on the page.
 *
 * In our init function above we supplied 'viewport > panel', which translates to "find me every Panel that is a direct
 * child of a Viewport". We then supplied an object that maps event names (just 'render' in this case) to handler
 * functions. The overall effect is that whenever any component that matches our selector fires a 'render' event, our
 * onPanelRendered function is called.
 *
 * ## Event domains
 *
 * In Ext JS 4.2, we introduced the concept of event domains. In terms of MVC, an event domain
 * is one or more base classes that fire events to which a Controller wants to listen. Besides
 * Component event domain that encompass {@link Ext.Component}-descended Views, Controllers now
 * can listen to events from data Stores, Ext.Direct Providers, other Controllers, and Ext.globalEvents.
 * This feature provides a way to communicate between parts of the whole application without the need
 * to bind controllers together tightly, and allows to develop and test application parts in isolation.
 *
 * See usage examples in {@link #listen} method documentation.
 *
 * ## Using refs
 *
 * One of the most useful parts of Controllers is the ref system. These use the {@link Ext.ComponentQuery} to
 * make it really easy to get references to Views on your page. Let's look at an example of this now:
 *
 *      Ext.define('MyApp.controller.Users', {
 *          extend: 'Ext.app.Controller',
 *          
 *          refs: [{
 *              ref: 'list',
 *              selector: 'grid'
 *          }],
 *          
 *          init: function() {
 *              this.control({
 *                  'button': {
 *                      click: this.refreshGrid
 *                  }
 *              });
 *          },
 *          
 *          refreshGrid: function() {
 *              this.getList().store.load();
 *          }
 *      });
 *
 * This example assumes the existence of a {@link Ext.grid.Panel Grid} on the page, which contains a single button to
 * refresh the Grid when clicked. In our refs array, we set up a reference to the grid. There are two parts to this -
 * the 'selector', which is a {@link Ext.ComponentQuery ComponentQuery} selector which finds any grid on the page and
 * assigns it to the reference 'list'.
 *
 * By giving the reference a name, we get a number of things for free. The first is the getList function that we use in
 * the refreshGrid method above. This is generated automatically by the Controller based on the name of our ref, which
 * was capitalized and prepended with get to go from 'list' to 'getList'.
 *
 * The way this works is that the first time getList is called by your code, the ComponentQuery selector is run and the
 * first component that matches the selector ('grid' in this case) will be returned. All future calls to getList will
 * use a cached reference to that grid. Usually it is advised to use a specific ComponentQuery selector that will only
 * match a single View in your application (in the case above our selector will match any grid on the page).
 *
 * Bringing it all together, our init function is called when the application boots, at which time we call this.control
 * to listen to any click on a {@link Ext.button.Button button} and call our refreshGrid function (again, this will
 * match any button on the page so we advise a more specific selector than just 'button', but have left it this way for
 * simplicity). When the button is clicked we use out getList function to refresh the grid.
 *
 * You can create any number of refs and control any number of components this way, simply adding more functions to
 * your Controller as you go. For an example of real-world usage of Controllers see the Feed Viewer example in the
 * examples/app/feed-viewer folder in the SDK download.
 *
 * ## Generated getter methods
 *
 * Refs aren't the only thing that generate convenient getter methods. Controllers often have to deal with Models and
 * Stores so the framework offers a couple of easy ways to get access to those too. Let's look at another example:
 *
 *      Ext.define('MyApp.controller.Users', {
 *          extend: 'Ext.app.Controller',
 *
 *          models: ['User'],
 *          stores: ['AllUsers', 'AdminUsers'],
 *
 *          init: function() {
 *              var User, allUsers, ed;
 *              
 *              User = this.getUserModel();
 *              allUsers = this.getAllUsersStore();
 *
 *              ed = new User({ name: 'Ed' });
 *              allUsers.add(ed);
 *          }
 *      });
 *
 * By specifying Models and Stores that the Controller cares about, it again dynamically loads them from the appropriate
 * locations (app/model/User.js, app/store/AllUsers.js and app/store/AdminUsers.js in this case) and creates getter
 * functions for them all. The example above will create a new User model instance and add it to the AllUsers Store.
 * Of course, you could do anything in this function but in this case we just did something simple to demonstrate the
 * functionality.
 *

 *
 * For more information about writing Ext JS 4 applications, please see the
 * [application architecture guide](#/guide/application_architecture). Also see the {@link Ext.app.Application}
 * documentation.

     *          },
     *          ...
     *      });
     * 
     * Is equivalent to:
     *
     *      Ext.define('AM.controller.Users', {
     *          init: function() {
     *              this.control({

     *
     * Of course, these can all be combined in a single call and used instead of
     * `control`, like so:
