using binary comparator

I did a quick test on the speed for using binary comparator and on a
simple group by query described in
http://wiki.apache.org/pig/PigPerformance I saw 22.5% performance
improvement. The time went from 17m52s to 13m51s.
 
I was hoping for a bit more but given that the change is pretty easy
this is still a reasonable improvement.
