Obviously, component is for controllers, helper is for views. The
reason for the helper is that often view output depends on what is in
the session, and it can get a little tedious set()'ing everything from
the session out for the view, in the app_controller beforeFilter
("just in case" the view needs it for this request).
You will notice that the session helper is read only - you cannot
write from the view. So while it may be a little against the grain of
MVC, it is also very handy :)
