By rwcarlsen:

I don't think we need to track state history within the simulation. I would recommend just using an auto-increment field in sqlite. I've been profiling cyclus a bit and the IsoVector class is a big time eater - its methods are called more than any other class. We need to think carefully about adding things to IsoVector because they can have a significant negative performance impact.
