Continued upgrades to graph generation service and disk based caching for DAOs (especially useful for the in memory database loading)
Graph generation speed is improved over previous refactorings, and is probably close to the old spagetti code as far as speed.  However there is much less duplicate code, and the process, especially for property graph building, is easier to understand.
Disk based loading now uses Kryo to serialize to disk, improving space by about 20% and speed by 800%. (2 minute load for 2 passes on 800Mb of data)
