/**
 * This class is an adapter wrapping around a local match listener so that it can be registered
 * as a remote match listeners. This adapter publishes an RMI interface and forwards
 * notification events from the server to the specified local listener. This removes the need
 * for local listeners to be remote objects.
 *
 * There are two reasons behind this class:
 * <UL><LI>Match front ends need only to implement LocalMatchListener and need not worry about
 *   RMI specific details</LI>.
 * <LI>Only this adapter needs to be in the game peer  and arena class path. Local listeners (which are
 *   usually game specific) need not. This allows new games to be added without having to install
 * them in every match front end and game peer.</LI>
 * </UL>
