+ * List of short aliases for class names. Most useful for defining xtypes for widgets:
+ *
+ * Ext.define('MyApp.CoolPanel', {
+ * extend: 'Ext.panel.Panel',
+ * alias: ['widget.coolpanel'],
+ * title: 'Yeah!'
+ * });
+ *
+ * // Using Ext.create
+ * Ext.widget('widget.coolpanel');
+ * // Using the shorthand for widgets and in xtypes
+ * Ext.widget('panel', {
+ * items: [
+ * {xtype: 'coolpanel', html: 'Foo'},
+ * {xtype: 'coolpanel', html: 'Bar'}
+ * ]
+ * });
