Forgive my ignorance, but where do QueryResponseWriters live? And where do
they fit into the flow? 

I know how the different components fit into a distributed search, and how
all the stages flow, but I haven't seen anything about response writers...

Would it be something like using the distributed search and components to
retrieve the doc_ids and facets, and once the entire distributed search is
complete, a ResponseWriter would take the results (which is just doc ids
since we didn't use the get_fields or any Database component), queries our
SQL database, and creates the final response that gets sent to the client?
