Fixed the indexing engine (again), but now there is no big-ass record and I'm moving towards the map crap, still needs review and help
Fixed the client query test and forced client queries to be sequences of documents
Prevented perpetual re-indexing when no new content is available
Ensured that when documents are modified, their old entries in the index are removed pre-indexing
Switched across to using pr-str for transport, should probably ask about the correctness of this
