To load all objects in this library consult the events.loader utility 
file.

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

The protocol event_handlersp declares the two basic event handler predicates
(before/3 and after/3). You will need to refer this protocol in your objects
if you need to use the super control structure (^^/1) with these predicates.

The monitor object implements more sophisticated event handling predicates.

Some of the objects assume that the used Prolog compiler defines the 
usual sort/2 built-in predicate.
