> Currently RowCounter only retrieves latest version for each row.
> Some applications would store multiple versions for the same row.
> RowCounter should accept a new parameter for the number of versions to return.
> Scan object would be configured with version parameter (for scan.maxVersions).
> Then the following API should be called:
> {code}
> public KeyValue[] raw() {
> {code}
