> hbase-480 adds a merge tool. Seems to work for two adjacent regions in tests but not
for the case where we've made two overlapping regions: i.e. both have a start key of 'A' but
one regions endkey is less than the end key of the others (See up on Lars cluster hbase-471).
 I ran the merge and it made a new region with the right start and end keys but there was
nothing in it.
> We need this tool to do fix up when hbase goes awry.
