/**
 * TODO: This class will eventually be more than just a wrapper for two ints. It
 * will eventually be created with some sort of BlindSchedule object that
 * contains how often blinds raise and the values of the small/big blinds at
 * each level. In addition, this class will eventually be responsible for
 * spitting out events to say "raise the blinds". That's why the class was moved
 * to be more closely associated with the Game domain and is independent from
 * the Table domain.
