New Revision: 698044

URL: http://svn.apache.org/viewvc?rev=698044&view=rev
Log:
PIG-441 Added object comparators to the PigXRawComparator classes so that in 
places where hadoop uses the object instead of null comparators the desc 
behavior
can still be handled.

Changed FindQuantiles UDF to take in its constructor an array that indicates 
ascending vs descending order so that the quantiles can be correclty computed.
