Logout events

Terry and all --

Session expiration events are an excellent idea! There's
very little  
we would need to do here, because we already have a session
monitor  
thread (SessionMonitor) that actually detects the
expirations. It  
would be a very simple thing to have that chunk of code fire
off this  
new event type (expiration) when it detects that a session
has expired.

As for session statistics, I've been tossing around a few
ideas in my  
head for a while about this. Basically, I've been thinking
that it  
would be great if we had a listener class that subscribes to
login/ 
logout/expiration events and page events and records a bunch
of  
stats. Things that might be interesting for session
statistics:
- Time of login, logout, and authentication change
(anonymous ->  
asserted -> authenticated)
- User name
- Length of session
- # pages read
- # pages edited

We'd need the new event type (for expirations), a listener
class  
("SessionStatsListener") and a class that would
contain stats for  
each session ("SessionStats"). There's also the
log file, which could  
be done through log4j but might be better executed through
standard  
file operations.

I don't have any plans to do this soon (not in the next 30
days,  
anyhow) but it would be an extremely straightforward thing
to do.
