[bfprog] autobalance

[Forrest Thiessen]

That's an interesting idea to balance based on score; seems like it
might be unstable, though (lots of team switching) early in games, but
then would stabilize later on.  Maybe some hysteresis could be added to
stabilize it, so that score-based switching only takes effect when the
*difference* between the scores of the two teams exceeds some threshold?

Python has hashes, just like Perl--it just calls them "dictionaries",
instead, and uses slightly different syntax, but they are the same
ever-useful animal.  Here's a nasty-looking link to the documentation on
how to use them:
    http://python.org/doc/2.3.5/tut/node7.html#SECTION007400000000000000000

I haven't tried this (and haven't given it much thought, either, so
there's probably a better way to to do it), but something like this
probably does what you want:

for player in bf2.playerManager.getPlayers():
    playerCount[player.getTeam()] += 1
