records system is dog slow, and should record EVERYTHING needed to recreate the solve or path

[ofloveandhate]

right now the homotopy doesn't get recorded, so it's impossible to retrack paths later in an independent run. so the ask record is incomplete.

also, it's dog slow to record from Python. if the recording system is worth its diskspace, it must be performant.

also, i want the record system to be able to tolerate the same system with different parameter values, so that i don't have to write the system a million times, just the million parameter values.
