		// summary:
		//		Lightweight version of Calendar widget aimed towards mobile use
		//
		// description:
		//		A simple GUI for choosing a date in the context of a monthly calendar.
		//		This widget can't be used in a form because it doesn't serialize the date to an
		//		`<input>` field.  For a form element, use dijit/form/DateTextBox instead.
		//
		//		Note that the parser takes all dates attributes passed in the
		//		[RFC 3339 format](http://www.faqs.org/rfcs/rfc3339.html), e.g. `2005-06-30T08:05:00-07:00`
		//		so that they are serializable and locale-independent.
		//
		//		Also note that this widget isn't keyboard accessible; use dijit.Calendar for that
		// example:
		//	|	var calendar = new dijit.CalendarLite({}, dojo.byId("calendarNode"));
		//
		// example:
		//	|	<div data-dojo-type="dijit/CalendarLite"></div>
