     *  A simple event repeater (proxy) that delegates all functionality to the
     *  listener sent into the ctor.  Useful if you want to listen in on a few
     *  debug events w/o interrupting the debugger.  Just subclass the repeater
     *  and override the methods you want to listen in on.  Remember to call
     *  the method in this class so the event will continue on to the original
     *  recipient.
