/**
* Notes:
*  This could also be done as a process of "registering" functions to perform the authentication,

* $c->authenticate_hook for a function to be called, or it just does the normal thing if
* that is not set.
*  It might be a better way.  I think I need to bounce these two ideas off some other people...
*
* In either case Session will need to split the fetching of session data from the fetching of
* usr data.  So I'll look at doing that first.
