Added: src/java/org/apache/jcs/engine/control/event/behavior
IElementEvent.java IElementEventConstants.java
IElementEventHandler.java
Log:
Adding an intial idea of how to handle simple events.
Two models:
1. register handlers with the element and have the handler decide which events to
act on.
2. register handlers for only those events that it wants to act on in the first
place.
The second makes handling multiple events a bit cumbersome.
