Fill in post processing function (in simulation folder)

[SeanMcOwen]

I can give an example here. In the past one way I did it was just saving a simulation log with a dictionary of the important variables during sim and then just straight converting it to pandas.

But one can also do anything taking from the state and parameters at the end of the simulation. So saving individual variable histories with loggers and then concatenating them works too

There is already a dummy function that returns nothing defined that just needs logic filled in but is wired up
