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