	<brief_description>
		A container that creates a tab for each child control, displaying only the active tab's control.
	</brief_description>
	<description>
		Arranges child controls into a tabbed view, creating a tab for each one. The active tab's corresponding control is made visible, while all other child controls are hidden. Ignores non-control children.
		[b]Note:[/b] The drawing of the clickable tabs is handled by this node; [TabBar] is not needed.
