  "Description": "A flexible framework for calculating Elo ratings and\nresulting rankings of any two-team-per-matchup system (chess,\nsports leagues, 'Go', etc.). This implementation is capable of\nevaluating a variety of matchups, Elo rating updates, and win\nprobabilities, all based on the basic Elo rating system. It\nalso includes methods to benchmark performance, including\nlogistic regression and Markov chain models.",
