 * Note: This class is here since the basic {@link Observer} interface is not exactly
 * what we need.  It requires that any observables extend the {@link Observable} class, 
 * which we can't do since the precludes extending other classes we DO need.  Hence the
 * need for this custom implementation of the Observer pattern.  Note that we still take 
 * advantage of the {@link Observer} interface but only use part of its definition.
