%description
A flexible framework for calculating Elo ratings and resulting rankings of
any two-team-per-matchup system (chess, sports leagues, 'Go', etc.). This
implementation is capable of evaluating a variety of matchups, Elo rating
updates, and win probabilities, all based on the basic Elo rating system.
It also includes methods to benchmark performance, including logistic
regression and Markov chain models.
