Wombat::MamaQueue::EnqueueEventForwarder

This class is used to forward messages from the enqueueEvent function to the instance of the MamaQueueCallback class that the client originally supplied. Note that multiple events may be enqueued before any of them are processed. To avoid the managed objects being collected references are stored in a Dictionary object. These are then removed whenever the relevant callback fires.
