PS2, Line 10: forward declare MergeIterState anymore.
another option here to consider is moving the definition of UnionIterator and 
MergeIterator into the .cc file, and then only expose factory methods (which 
return the super-interface type instead of the underlying impl types). Would 
that work or do callers need the specific impl types?

(not a big deal, just wondering if it would be just as easy and improve 
compilation time and encapsulation)
