public abstract void	destroy() Terminate this messenger and let it clean-up it's trash (jni trash or sockets and stuff).
public abstract boolean	initialize() Used to initialize the platform specific initialisation.
protected final void	onMessageReceived(String message) To be called by the messengers that extend this class.
public final void	removeListener(MessageListenerInterface listener) Removes a previously added listener.
public abstract boolean	sendMessage(String message) Messengers should override this method with their sendMessage implementation, dependant on the platform.
