Gabriel Reid updated CRUNCH-554:
--------------------------------
Attachment: CRUNCH-554.patch
Patch to add MAX_COMPARABLES and MIN_COMPARABLES to the Aggregators class, also
removes the existing min and max aggregators for various numeric types.
One extra thing I was considering was deprecating the MIN_<numeric type> and
MAX_<numeric type> aggregators, with the suggestion to just use the
MAX_COMPARABLES and MIN_COMPARABLES methods instead. Anyone have any thoughts
either way on that?

> In the Aggregators class, we currently have min and max aggregators for
> various numeric types, but not for the general case of Comparables. We do
> have this functionality in the MaxN and MinN aggregators, however.
> We should add MAX_COMPARABLES and MIN_COMPARABLES methods to the Aggregators
> class. As extra bonus, all of the current numeric max and min aggregators can
> be discarded and replaced with the comparable version.
