Review request for hbase and Michael Stack.
Changes
-------
Linking the HBASE-4062 JIRA to this review.
Summary
-------
Adding a unit test for the multi-column scanner. We are using this this to test
an optimization we are making to multi-column scans using row-column Bloom
filters. The scanner creates multiple StoreFiles for a single column family,
each containing a randomized set of columns with different timestamps, and then
tests scanning through the whole region with all possible sets of columns
specified in the query. Point deletes (deletes of a specific timestamp) are
also tested.
This addresses bug HBASE-4062.

Testing
-------
Run the unit test. Break the store scanner and make sure the test breaks.
Thanks,
