@---+ Package =TWiki::User=

A User object is an internal representation of a user in the real world.
The object knows about users having login names, wiki names, personal
topics, and email addresses.


%TOC%

Groups are also handled here. A group is really a subclass of a user,
in that it is a user with a set of users within it.

The User package also provides methods for managing the passwords of the
user.

The wiki name can either be a wiki word or it can be a web-

user is assumed to have their home topic in the
$TWiki::cfg{UsersWebName} web.
