Disable the cache file and make the default hands 11th street, since all
we're doing is benchmarking stuff.
Merge remote-tracking branch 'origin/master'
Merge pull request #5 from abliss/speedup3

On 13th st, precalculate all P2 hands. 4x speedup!
Stop mucking up classpath.  Why is this submitted anyways?
Remove some unused and confusing duplicate code
This is embarassing.  Make trove work.  Very minor or nonexistent
speedup, but presumably lowers memory usage.

Also make the default test case 10.5 street and reduce the frequency
that instrumentation is output.
