Looks good to me, matches my code for python bindings.

Only point I'd raise is high-level: why does TRCF only have a process() method while RCF has score(), update(), etc? Can we add a little more detail to what TRCF.process() does - is it basically "score and update"?

In a future commit I think we'd also want to add more on the documentation side, especially regarding the RCF / TRCF parameters and their meaning.

process does more than score/update. It includes all of the pre and post processing besides score/update. I added more description on the process method parameters.
