Title: An implementation of the TrueSkill algorithm in R
Description:
An R implementation of the TrueSkill Algorithm (Herbrich, R., Minka, T. and Grapel, T),
a Bayesian skill rating system with inference by approximate message passing on a factor graph.
Used by Xbox to rank gamers and identify appropriate matches.

Requires R version 3.0 as it is written with Reference Classes.

Example:
Team1 <- Team("T1", rank = 1, list(Player("Alice", Gaussian(25, 8.3))))
Team2 <- Team("T1", rank = 2, list(Player("Bob", Gaussian(25, 8.3))))
teams <- list(Team1, Team2)
epsilon <- DrawMargin(draw_probability = 0.1, beta = 25 / 6, num_teams = 2)
parameters <- Parameters(beta = 25/6, epsilon, 25 / 300)
teams <- Trueskill(teams, parameters)
