Why only check1-and-putMany and check1-and-deleteMany?
If I understand correctly, an HTable has two composite atomic operations,
checkAndPut and checkAndDelete.  The check part checks just a single
column's value.  Why not allow checking more than one column?

Why no checkAndAppend?

The checkAndPut operation can put to multiple columns, right?  And the
checkAndDelete operation can delete multiple columns, right?  Why not let
them be mixed?  Why not checkAndMutate?

Thanks!
Mike
