+/** 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.
