Josh Wills updated CRUNCH-376:
------------------------------
Attachment: CRUNCH-376b.patch
Put this into patch form-- [~jgmath2000], one concern: the result of an
Aggregator call isn't necessarily a single value (e.g., a TOP_N aggregation).
I'm trying to think of a clean way to represent both the single-valued and
multi-valued aggregations.
> Add aggregate(...) function to PCollection
