Pipers now only look in their section
Added lots of 9s to the two piper speeds
no drops on handoff, no rats plucked off by fence, skeleton for full case configuration
for sweep case, pipers fan out over top edge
Accounted for all cases; sweep works; took out handoffs of rats
Fixed slowness bug and greedy bug on greedy sweep
make choice of strategy contingent on number of rats left on the board (dynamic)
