Some examples of the use of SimpleCAS.

SimpleCAS_Local.inc: Is an example showing how to subclass the standard
	SimpleCAS class to default to your CAS server.  It needs to have
	its require_once statement adjusted to point to your SimpleCAS
	include file.

The examples below all assume a SimpleCAS_Local.inc pointing to your
CAS server.  You will need to adjust the require_once statement to point
to your include file.

simple_example.php4: This is a simple example.  Only people with validly
	authenticated via CAS can see anything.  Authenticated users get
	a simple welcome message.

complicated_example.php4: This is a more complicated example of what can
	be done.  It supports 3 levels of authentication:
	unauthenticated users just see some public information
	authenticated users see public and secret information
	top secret information requires you to validate with your
	password (cannot just be validated via TGT cookie), and
	your username must be jamesbond.  It also shows some information
	regarding the session, so can watch the session id get 
	regenerated after 15 minutes (you would not normally print session id)
