		// summary:
		//		A dialog box for mobile.
		// description:
		//		SimpleDialog is a dialog box for mobile.
		//		When a SimpleDialog is created, it is initially hidden and not
		//		displayed (display="none"). To show the dialog box, you need to
		//		get a reference to the widget and to call its show() method.
		//
		//		The contents can be arbitrary HTML, text, or widgets. Note,
		//		however, that the widget is initially hidden. You need to be
		//		careful when you place something that cannot be initialized
		//		under the hidden state into a SimpleDialog.
		//
		//		This widget has much less functionalities than dijit/Dialog, 
		//		but it has the advantage of a much smaller code size.

		// top: String
		//		The top edge position of the widget. If "auto", the widget is
		//		placed at the middle of the screen. Otherwise, the value
		//		(ex. "20px") is used as the top style of widget's domNode.
		top: "auto",

		// left: String
		//		The left edge position of the widget. If "auto", the widget is
		//		placed at the center of the screen. Otherwise, the value
		//		(ex. "20px") is used as the left style of widget's domNode.
		left: "auto",

		// modal: Boolean
		//		If true, a translucent cover is added over the entire page to

		//		top-right corner.
