TurbineUser(Peer) is written so that additional columns can be added to the
Visitor table. The column values are then available through
turbineUser.getPerm("fullcolumnname").
This is a quick solution, if you can live with casting your attributes
whenever you want to use them.
Otherwise write your own XTurbineUser, etc. I do not think you gain much by
subclassing the Peer, as I do not know of any way in Java to dynamically
cast. But you can cut-and-paste the code from TurbineUserPeer. I would say
this is the correct way to go if your User object contains much additional
functionality. TurbineUser obviously doesn't model every situation.
