//It's common for an object to want to create and own a Broadcaster and set
//itself as a Listener on its own Broadcaster member.
//However, calling addListener on a Broadcaster means that the Broadcaster adds
//a reference to the Listener leading to an ownership cycle where the Listener
//owns the Broadcaster which "owns" the Listener.
//The WeakContainerListener allows breaking this cycle and retrofitting
//afflicted implementations fairly easily.
//OriginalListener owns the Broadcaster which "owns" the WeakContainerListener
//which forwards the events to the OriginalListener without taking ownership of
//it.
