> Use binary comparison in data types

>
> Currently, each data type in Pig has compareTo function as the means to
> compare objects during maps side sort. This is very inefficient since 2
> objects need to be created for each comparison. Using binary comparison
> should speed things up significantly(2-3x) for most queries.
