/**
 * This class links a layout with other class which provides components to it. It is useful
 * whenever (reusable) part of a layout should be programmed as a separate class, but its components should
 * be added to layout directly to obtain uniform presentation (think about {@link FormLayout}).
 * 
 * This class provides operations to add/remove components, which are proxied to the layout.
