Well, it isn't too hard to understand it by reading code.  However,
some explanations about id are needed.  Roster holds two mappings:
jid2id and id2jid.  Id's are just numbers used to identify a contact
items in list (there can be many list items for one contact because a
person can be present in several groups).  This allows us to find all
items for a specific jid very easily.  Just the same about 'group2id'
and 'id2group' maps.  An additional info about group is stored in
'groupinfo' dictionary.  This info is used to draw group properly on
the screen.

To display various information in work roster registers it's own
handlers for such events as presence info updates (to show online
status of a user), message arrival (to show a little message icon near
contact name) and so on.  No other parts of program should operate on
roster directly.  Instead they should 'fire_event()' and, if roster
has a handler for this message, it will do what needed.  See
'MessageRead' event handling when I'll be done with messaging.

I hope this explanation is understandable.  If you still have
questions, ask'em!
