events

The objects event_registry, before_event_registry, and after_event_registry implement convenient predicates for registering before and after events.

The code makes use of the monitoring built-in protocol, which declares the two basic event handler predicates (before/3 and after/3). You will need to refer to this protocol in your objects if you want to use the super control structure `(^^/1)` with these predicates.

The monitor object implements more sophisticated event handling predicates.
