Wave 1 pair progrramming (Commit Dec12-19): Alyssa & Maya

Trello Board: https://trello.com/b/j5XOx7cU/alyssa-maya-tic-tac-toe

Critical Design Decisions:

1. Three Objects: Game, Player and Board;
2. A Game has two players, multiple rounds and a new board for each round;
3. A round has multiple moves;
4. A new round automatically starts when there is a winner or a tied game;
5. Round starter switches in turns for each round;
6. Score is an attribute of Player, and increments in Game.move;
7. Winner's score increments by 2, loser's score increments by 0, tied game both players' scores increments by 1.

Used TDD. All testing completed with full coverage.

WE ROCK!!! YAY!
