Subject: [PATCH] Removed need to keep track of counter, which reduces
 complexity and chance of introducing errors, by slicing the the units tuple
 by the percision.  Removed __main__ because nosetest --with-coverage was
 flagging it.  It was un-nessasary.

Special thanks to Eric Rasmussen who inspired this commit.
