	//	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.
