This class is a very flexible event dispatcher which implements Runnable so that it can
dispatch easily from a newly created thread. The usage of this in code is more or less:
create a new instance of this class, use addListenerTriplet to add as many listeners
as desired to be messaged, create a new Thread using the instance of this class created
as the argument to the constructor, start the new Thread instance.
Also, this is intended to be used to message methods that either return void, or have
a return which the developer using this class is uninterested in receiving.
Add a listener triplet - the instance of the listener to be messaged, the Method on which
the listener should be messaged, and the Object array of arguments to be supplied to the
Method. No attempts are made to determine whether this triplet was already added.
Messages are dispatched in the order in which they're added via this method; so if triplet
X is added after triplet Z, then triplet Z will undergo messaging prior to triplet X.
This method should not be called once the owning Thread instance has been started; if it
is called, the triplet will not be added to the messaging queue.
listenerInstance - the instance of the listener to receive the associated notification
listenerMethod - the Method instance representing the method through which notification
methodArguments - the arguments supplied to the notification method
