Is node-trueskill usable for *team* matches? #2

Trueskill algorithm from Microsoft fits team matches, not only single player ones) (see http://boson.research.microsoft.com/trueskillranking/rankcalculator.aspx). Does your implementation allows this scenario? If yes, can you please document it someway? (a simple example on the README should be great...)

I did not need it for my use case. There is a comment in the code that addresses team matches.

  # Create all the variable nodes in the graph.  "Teams" are each a
  # single player; there's a one-to-one correspondence between players
  # and teams.  (It would be straightforward to make multiplayer
  # teams, but it's not needed for my current purposes.)

If you end up adding it I would gladly check your work (math can be a lil tricky) and/or accept a pull request.

I see... Sorry, I missed your comment on coffe source. Unfortunately I find math behind Trueskill quite tricky... And, I don't use coffescript for everyday work... However I'll watch this project, if somebody will implement team matches... :-)
