Description copied from class: PigBytesRawComparator

Compare two NullableBytesWritables as raw bytes. If both are null, then the indices are compared. If neither are null and both are bytearrays, then direct Writable.compareBytes is used. For non-bytearrays, we use BinInterSedesTupleRawComparator. If either is null, null one is defined to be less.
