/*  The game of tic tac toe.  The game is represented as a 3x3 grid of characters
 * 	which will either be a ' ', 'X', or 'O'.  The user will enter the square they
 *	want as two indices, i and j, between 1 and 3.  Since Java starts arrays at 0,
 *	we will have to manipulate the user's choice by subtracting 1 from each of i and j.
