Do we really want to create yet another way to muck with data? Any reason
we can't use the `RowSet` concepts here? I fear that if we have multiple ways
to do the same thing, we won't achieve critical mass on any of them and we'll
have a bunch of half-baked solutions. I'd rather have one fully-baked solution
we use over and over. Allows new tests to get done easily because the required
tools already exist. This, in turn, encourages testing.
What are we doing here that `RowSet` can't (yet) do?
> Make code generation in the TopN operator more modular and test it
