% "Extract cell index/item"
% Nabs a cell array with just specified index of any query (query, equery, aquery, pquery, kquery).
%
% This is just a fancier-named version for a generic method to get individual element from cell array from >2-tuples (which is another fancy way of saying a cell array of >2-length cell arrays) that is needlessly and arbitrarilymade exclusive to ChessBoard queries. So there's that!

% { chesspiece, coords }, so type = 1 or 2

% nvm ignore all above, it is fixed and i am sad
