	// summary
	//	Provides Delphi-style panel layout semantics.
	//
	// details
	//	A LayoutContainer is a box with a specified size (like style="width: 500px; height: 500px;"),
	//	that contains children widgets marked with "layoutAlign" of "left", "right", "bottom", "top", and "client".
	//	It takes it's children marked as left/top/bottom/right, and lays them out along the edges of the box,
	//	and then it takes the child marked "client" and puts it into the remaining space in the middle.
	//
	//  Left/right positioning is similar to CSS's "float: left" and "float: right",
	//	and top/bottom positioning would be similar to "float: top" and "float: bottom", if there were such
	//	CSS.
	//
	//	Note that there can only be one client element, but there can be multiple left, right, top,
	//	or bottom elements.
	//
	// usage
	//	<style>
	//		html, body{ height: 100%; width: 100%; }
	//	</style>
	//	<div dojoType="LayoutContainer" style="width: 100%; height: 100%">
	//		<div dojoType="ContentPane" layoutAlign="top">header text</div>
	//		<div dojoType="ContentPane" layoutAlign="left" style="width: 200px;">table of contents</div>
	//		<div dojoType="ContentPane" layoutAlign="client">client area</div>
	//	</div>
	//
	//	Lays out each child in the natural order the children occur in.
	//	Basically each child is laid out into the "remaining space", where "remaining space" is initially
	//	the content area of this widget, but is reduced to a smaller rectangle each time a child is added.
	//

		dijit.layout.layoutChildren(this.domNode, this._contentBox, this.getChildren());
