	//		A textarea that dynamically expands/contracts (changing it's height) as
	//		the user types, to display all the text without requiring a scroll bar.
	//
	//		Takes nearly all the parameters (name, value, etc.) that a vanilla textarea takes.
	//		Rows is not supported since this widget adjusts the height.
	//
	// example:
	// |	<textarea data-dojo-type="dijit.form.TextArea">...</textarea>
