[OkayAlright]

Currently, in writer_csv_util, there is a way to write out the entire CSV as a json using the ID tag as a hash-index and everything else is nested under that. There should be a way to more generically do this. Point at a column, use that as the hash-index.

It should also be smart enough to append fields with some prefix (like "entry-<id # or something>") if more than one entry exists with the same hash-index.
