react tic-tac-toe

this is my implementation of tic-tac-toe based on react's tutorial

i've also added some of their suggested ideas for improvement below:

1. For the current move only, show “You are at move #…” instead of a button.
2. Rewrite Board to use two loops to make the squares instead of hardcoding them.
3. Add a toggle button that lets you sort the moves in either ascending or descending order.
4. When someone wins, highlight the three squares that caused the win (and when no one wins, display a message about the result being a draw).
5. Display the location for each move in the format (row, col) in the move history list.
