[Proposal] Provide support for OLAP to OLTP to OLAP to OLTP

      Description

      I'm trying to figure out how we can, within a "single traversal", move between OLAP and OLTP at different sections of the traversal. E.g.

      [g.V.out.has('age',lt,25)]OLAP[out('parent').out('workPlace')]OLTP[out('coworkers').age.groupCount]OLAP
      

      Going from OLAP to OLTP is easy. We have solved that already as OLAP queries return a Traversal<S,E> and thus, can be further processed in OLTP. But what about going from OLTP back into OLAP? We need to be able to stream the OLTP results back into traversers on the vertices of the graph – TinkerGraph (easy), Hadoop (dynamic editing of the disk format!? crazy) .. is there a general pattern that works for all graphs? Finally, what about when the objects are NOT vertices/edges/etc. See the next issue.
