/**
- * @class Ext.picker.Date
- * @extends Ext.Component
- * <p>A date picker. This class is used by the {@link Ext.form.field.Date} field to allow browsing and
- * selection of valid dates in a popup next to the field, but may also be used with other components.</p>
- * <p>Typically you will need to implement a handler function to be notified when the user chooses a color from the
- * picker; you can register the handler using the {@link #select} event, or by implementing the {@link #handler}
- * method.</p>
- * <p>By default the user will be allowed to pick any date; this can be changed by using the {@link #minDate},
- * {@link #maxDate}, {@link #disabledDays}, {@link #disabledDatesRE}, and/or {@link #disabledDates} configs.</p>
- * <p>All the string values documented below may be overridden by including an Ext locale file in your page.</p>
- * <p>Example usage:</p>
- * <pre><code>new Ext.panel.Panel({
-    title: 'Choose a future date:',
-    width: 200,
-    bodyPadding: 10,
-    renderTo: Ext.getBody(),
-    items: [{
-        xtype: 'datepicker',
-        minDate: new Date(),
-        handler: function(picker, date) {
-            // do something with the selected date
-        }
-    }]
-});</code></pre>
