distractorScorefunction
How tempting candidate is as a wrong answer for target, from 0 up to 200: 100 for a land neighbour, 60 for
the same group, and up to 40 for being close, measured against diagonal, the corner-to-corner length of the map
(each map is drawn on a canvas of its own, so a distance only means something relative to it).
