Sorry, didn't get a chance to dial in last night.
accumulate_influence was 60 seconds, and scan_for_patterns() was
52 seconds. do_push_owl() or something like that was a close third,
then other functions were further behind.
I wonder if influence is more costly early in the game, when it
has to propagage a long way through an empty board and there aren't
so many patterns. But then later in the game, influence becomes less important,
and patterns more so..?
