A bloody battle for which I have emerged victorious though severely wounded. GremlinTracker provides all the Holder indexing for the vertex, its incident properties, edges, as well as its locally produced objects. GremlinMessage now contains the logic for message propagation in the swarm computing paradigm. There is a notion of a 'label future' for a Holder --- what Pipe will I be at next (this needs more work/thought but for Gremlin OLAP is necessary as it currently stands). Various other small tweaks here and there. In short, a battle galour.
