Josh Elser commented on ACCUMULO-2177:
--------------------------------------

FirstEntryInRowIterator would be a nice starting point here -- would be easy to (re)implement
a FirstEntryInRowIterator given a FirstNEntriesInRowIterator.

> I have found this iterator extremely useful when it is important to run a batch scan
over a bunch of different ranges but guarantee that a predefined number of results get returned
for each row.
