Description [src]

In crossword vernacular, an unch is an unchecked cell in a puzzle. That is to say, a white square that is part of only one answer (either across or down, but not both).

This function returns a list of all the cells it finds that are unches in the puzzle. These are only calculated for Standard and Cryptic crosswords. For standard crossword, it returns classic unches, but for Cryptics it’s less useful. In that case, it only includes runs of three unches in a row, or two in a row at the start/end of words.
