Callback Support

Simple Proxy class to avoid writing for loop to trigger multiple callbacks/listeners 

Before

// onMessage1()
for(Callback cb: callbackList) {
  cb.onMessage1();
}

// onMessage2()
for(Callback cb: callbackList) {
  cb.onMessage2();
}

Now

Callback cb = (Callback) proxyClass.getMulticaster();

// onMessage1()
cb.onMessage1();

// onMessage2()
cb.onMessage2();
