Detailed Description

Interface used to track connections between signals and slots.

Performs automatic connection and disconnection when either the slot or signal dies.

 class MyApp : public ConnectionTracker
 {
   Button.ClickedSignal().Connect( this, &MyApp::OnPress );

   void OnPress()
   {
     std::cout << "hello world" << std::endl;
   }
 }

When MyApp is destroyed, it automatically disconnects from Button.ClickSignal. It provides a signal observer interface, to observer when signals are destroyed e.g. if Button object is destroyed while it is still connected.
