> HBASE-47 added specification of TTL on cells.  The implementation checks cell timestamp against configured TTL before returning results scanning or getting.  You can also set the maximum versions of a cell to keep.  The maximum versions is not checked scanning or getting, only when we compact (We'll drop cells that are beyond the maximum version at compaction time).  This issue is about adding check for maximum versions to gets and scans so that if you ask for all versions but have configured the store to only keep 3 versions, though 4 may have been inserted, you'll currently get 4 returned (if compactions have not had a chance to run).
