-Implement a way to edit board position in runtime and start the game with the immediate position as an alternative to start game with FEN string.

(Done)Making the chess game having an option to pick from the 2 types of AI for which best move is produced, meaning at any chess position during the game, the ELO of the move can be different instead of fixed ELO during the whole game.

-Improve puzzle where multiple valid moves within a board position is possible.

-The board on scene will display files(columns) and ranks(rows).

(Done)Display captured pieces on scene.
