> Current limitations:
> Only a one long key test currently.  Need more tests.
> The hive-jmh test doesn't handle multiple iterations.  And, the number of rows and keys
being driven through is way too small to be meaningful.
> The focus of this change was to get things started.
> NOTE: This change does change main line code by adding test hooks.
