    Attachment: CRUNCH-181.patch

Yeah, exactly. It occurred to me that we could do a version that uses ByteBuffers, which will
have less overhead than Pairs-- what do you think?

> UUID is a pretty basic and common datatype used for identifiers.  It'd be nice if there
was support through Writables.uuids() similar to other common data types.
> The lack of support is most likely due to the lack of formal UUIDWritable support in
Hadoop itself but a UUIDWritable implementation has been posted for awhile[1] and seems pretty
trivial to even roll your own and incorporate.
