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. @see DebugEventHub
