scoreAreafunction

The area score: every stone on the board, plus every empty region whose only neighbours are one colour. An empty region touching both colours, or touching neither (an empty board), counts for nobody — dame, not territory. Dead stones are not marked or removed here: a stone left on the board still counts as a stone, so a player who wants credit for territory a stray stone sits in has to capture it before passing, the same as playing it out at the real table.
