Detailed Description
An interface to allow a standard method of trapping events.
Trappers get first dibs on events and can prevent the event from being sent any further
This is handy in situations where an event is more than a notification, and must be "handled" - the trapper which handles it returns true, otherwise it is passed to the next one
A trapper can filter any and all events, EXCEPT timers. This *could* be changed, if a good reason is presented.
