conflictsOffunction

THE CELLS THAT BREAK A RULE RIGHT NOW, read from the rules alone: no answer is needed, so it works on any puzzle, and it names a mistake the moment it is made rather than when it is checked.

values is the whole grid as it stands: the printed numbers and what has been written, row-major, 0 for empty. A cell is in conflict when it shares a row, a column, a box, a region, a diagonal or a cage with a cell holding the same number; when a cage is full and does not add to its sum, or already adds to more; when a more-than mark between two filled cells is not true; or when the cells from a Towers clue show more towers than the clue says (or, once the line is full, any other number). An empty cell is never in conflict, and a grid with no conflict is not thereby right: it may simply not be finished.
