Add fold decorator
This adds:
- An algorithm that adds a random number to each jet, based on the event number.
- A new top level script that runs this algorithm.
- A bunch of stuff I ported over from !554 so that I could save an unsigned int off a jet.
The last point was a bit unfortunate to bundle in with this one, but I didn't want to add any more functionality that I'd already replaced in !554. I ran a diff and saw no differences in the output with this restructuring.
@svanstro, I'd like to get this in so you can submit some jobs. I'll start working on some other cleanup MRs in the meantime.
