New puzzle: `Slant', picked from the Japanese-language section of nikoli.co.jp (which has quite a few puzzles that they don't seem to have bothered to translate into English). Minor structural change: the disjoint set forest code used in the Net solver has come in handy again, so I've moved it out into its own module dsf.c. [originally from svn r6155]
