/**
 * A Game to be played using the Die.java random die generator
 *
 * The player rolls a ten-sided die and a six-sided die,attempting to get as close to 11 as possible without
 * going over. If the player gets 11 exactly, they
 * automatically win, but if they go over 11, the computer automatically wins.  After both dies have been
 * rolled once, one of them can be rolled again to attempt a better total. The computer will always re-roll
 * the smaller die if they have a lower score than the human player.
