| A StackLayout object is a layout manager for a container. It 
		treats each component in the container as a card. Only one card is 
		visible at a time, and the container acts as a stack of cards. The first 
		component added to a StackLayout object is the visible component 
		when the container is first displayed. The ordering of cards is 
		determined by the container's own internal ordering of its component 
		objects. StackLayout defines a set of methods that allow an 
		application to flip through these cards sequentially, or to show a 
		specified card. Main Features
