Java Pig Game

// Pig Game
// Driver class using PairOfDice that plays a game of pig.  On each turn, the player rolls a pair of dice and adds up his or her points.
// Whoever reaches 100 points first, wins. If a player rolls a 1, he or she loses all points for that round and the dice go to the other player.
// If a player rolls two, 1s in one turn, the player loses all points earned so far in the game and loses control of the dice.
// The player may voluntarily turn over the dice after each roll. So the player must decide to either roll again (be a pig) and risk losing points,
// or give up the dice, possibly letting the other player win. Comp gives up dice after winning 20 points in one round.
