"""
This file implements all methods necessary for working with users and
sessions in Invenio. Contains methods for logging/registration
when a user log/register into the system, checking if it is a guest
user or not.
At the same time this presents all the stuff it could need with
sessions managements, working with websession.
It also contains Apache-related user authentication stuff.
