/// <summary>
/// In this function the AiS letters are parsed from external classes to actually make
/// a move (This function uses all the other functions found in this class to make a move).
/// It does this by first generating all possible moves, it then parsed these possible
/// words into a generateAllMovesForAllWords to try and generate all the moves possible.
/// If it failes to do this then this means there is no moves possible for the ai to make.
/// if there is an avaliable move the ai will tell the game engine to make the move.
///
/// The Function also uses a GrabATile variable to check if the ai has actually used any of its
/// tiles, this is a relic when one of the newer move conditions was not introduced (DrawnATile).
/// I left the check still in as a backup to prevent the ai being caught in a logic loop. This
/// is where the ai would make its best move without using any of its tiles and not drawing any
/// new tiles, meaning the ai would be stuck making the same move over and over again.
