Making a tic-tac-toe game with python. 

Features and plans to add:

2. Take in player inputs from player a and b

3. Display input on game board

4. Create functions that will check for winners, losers or possible ties

5. Switch player

6. Check if the player won or lost or tie from his side

5. If no result occurs, continue playing or else announce winner or announce its a tie

6. Ask if they want to play again
