/**
 * A MultiCallBackable object is required for each MultiBox that is created.
 * It is called back when sorting of elements is required, and when events
 * are received. 
 * <P>
 * The MultiCallBackable things are currently the two Containers.
 * Currently, MultiCallBackable also associates to a MultiWindow, or its equivalent, and
 * provides various information, as well as processing of actions.
 * This allows MultiBox and MultiWindow to be generic, while all processing
 * is centralised in the MultiCallBackable Object.
