Review comment:
This is *not* a simplification; it exposes too much detail. Better:
```
RowSetFormatter.print(rowSet);
```
Of course, if we go this route, we might as well leave the `print()` method
in `RowSet` and have it call the above code.
Just to be clear, the purpose of `print()` is to help us developers
visualize what's going on in Drill; it is not for production use. This is
important because, if you can't visualize a batch, you'll make many mistakes
because you can't tell what's what.
