// Package rps is an example of veyron service for playing the game of
// Rock-Paper-Scissors. (http://en.wikipedia.org/wiki/Rock-paper-scissors)
//
// There are three different roles in the game:
//
// 1. Judge: A judge enforces the rules of the game and decides who
//    the winner is. At the end of the game, the judge reports the
//    final score to all the score keepers.
//
// 2. Player: A player can ask a judge to start a new game, it can
//    challenge another player, and it can play a game.
//
// 3. ScoreKeeper: A score keeper receives the final score for a game
//    after it ended.
