/**
* Users
* Pokemon Showdown - http://pokemonshowdown.com/
*
* Most of the communication with users happens here.
*
* There are two object types this file introduces:
* User and Connection.
*
* A User object is a user, identified by username. A guest has a
* username in the form "Guest 12". Any user whose username starts
* with "Guest" must be a guest; normal users are not allowed to
* use usernames starting with "Guest".
*
* A User can be connected to Pokemon Showdown from any number of tabs
* or computers at the same time. Each connection is represented by
* a Connection object. A user tracks its connections in
* user.connections - if this array is empty, the user is offline.
*
* Get a user by username with Users.get
* (scroll down to its definition for details)
