/**
 * A menu containing an Ext.picker.Date Component.
 *
 * Notes:
 *
 * - Although not listed here, the **constructor** for this class accepts all of the
 *   configuration options of **{@link Ext.picker.Date}**.
 * - If subclassing DateMenu, any configuration options for the DatePicker must be applied
 *   to the **initialConfig** property of the DateMenu. Applying {@link Ext.picker.Date Date Picker}
 *   configuration settings to **this** will **not** affect the Date Picker's configuration.
 *
 * Example:
 *
 *     @example
 *     var dateMenu = Ext.create('Ext.menu.DatePicker', {
 *         handler: function(dp, date){
 *             Ext.Msg.alert('Date Selected', 'You selected ' + Ext.Date.format(date, 'M j, Y'));
 *         }
 *     });
 *
 *     Ext.create('Ext.menu.Menu', {
 *         width: 100,
 *         height: 90,
 *         floating: false,  // usually you want this set to True (default)
 *         renderTo: Ext.getBody(),  // usually rendered by it's containing component
 *         items: [{
 *             text: 'choose a date',
 *             menu: dateMenu
 *         },{
 *             iconCls: 'add16',
 *             text: 'icon item'
 *         },{
 *             text: 'regular item'
 *         }]
 *     });
