moveIsValid.h

/*

--> This function is to check whether the move made by the human is valid.
--> Here side is set to true.

NOTE:
WITHIN THE CODE HUMAN IS ALWAYS REFERRED AS WHITE (IN BOOLEAN AS TRUE)
AND THE COMPUTER IS ALWAYS REFERRED AS BLACK (IN BOOLEAN AS FALSE)
IRRESPECTIVE OF THE SIDE THE HUMAN CHOOSES AS HIS/HER OWN.

RETURN VALUE
1  -> The move is valid
-1 -> The piece name entered is wrong
-2 -> The piece is already captured
-3 -> The "goTo" position is not within the board
-4 -> The entered piece can't make that move
-5 -> The entered move is putting king under attack
