/**
This is the Score class for duels. This code is
basically what is included in Fractal and Cake to keep
score.

Instantiate this once on match start, and at the top
of all the needed events just pass them to the instance.
Call printScore at any time to print the scores to
the console. Call getScore(id) at any time to get the
score of the requested robot (0 = self, 1 = enemy).

If you'd like to use this in your robot, feel free to,
but give credit! -- Vuen
