Generate a graph for the icfp14 paper attempt.
Found some more untried working test cases.
Classified the rest of the sketch tests.
Changed interface to nqueens representations.

So that output display is now all common to nqueens.hs, so I can more easily
have a mode which lets me measure how high an n a representation reaches in a
given amount of time.
Updated perf gathering.
Made a mode where many n can be tried. Updated perf gathering.
Made the BitOneHotCell less stupid.
