Experiment over with pro

* Console and pro metrics not as useful as previously hoped. Switching
  focus to using free in interesting ways instead.
* Generalized breakout to take a variable number of levels to nest.
Bug fixes

* Stopped closing over old database values during the merge process.
* Hunted down the timeout causing transactions. There were several
  thousand records getting merged all at once that were taking longer
  than the 10 second minimum. Increased this minimum by two orders of
  magnitude. This removes the need to partition datoms, which was
  mangling transaction information.
* Simple command line arguments usage bug fix.
