    /**
     * 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'
     *         }]
     *     });
