BoxChildLayout class

Adapter that makes a Box compatible with the layout system.

BoxChildLayout implements the ChildLayout interface for Box objects, allowing boxes to participate as children in layout calculations. It provides the bridge between the box-based layout system and the generic layout algorithm interface.
