         *
         * In some cases, it is helpful to create a nested scope to contain some private
         * properties. The best way to do this is to pass a function instead of an object
         * as the second parameter. This function will be called to produce the class
         * body:
         *
         *      Ext.define('MyApp.foo.Bar', function () {
         *          var id = 0;

         *              }
         *          };
         *      });
         *
         * When using this form of `Ext.define`, the function is passed a reference to its
         * class. This can be used as an efficient way to access any static properties you
         * may have:
         *
         *      Ext.define('MyApp.foo.Bar', function (Bar) {
         *          return {
         *              statics: {
         *                  staticMethod: function () {
         *                      // ...
         *                  }
         *              },
         *
         *              method: function () {
         *                  return Bar.staticMethod();
         *              }
         *          };
         *      });
         *
         * To define 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',
         *
         *          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 of overrides 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
         *              //...
         *          }
         *      });
         *
         * 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
         *              }
         *          }
         *      });
         *
         * @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
         * Pass `null` to create an anonymous class.
         * @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:
         *  - `mixins`
         *  - `statics`
         *  - `config`
         *  - `alias`

         *  - `singleton`
         *  - `alternateClassName`
         *  - `override`
         *
         * @param {Function} createdFn Optional callback to execute after the class is created, the execution scope of which
         * (`this`) will be the newly created class itself.
         * @return {Ext.Base}
