The text says that gamma.mu is a required argument, but apparently it is not anymore? Looks like it was split into two hyperparameters @sebffischer @bblodfon

Yes, we split it so that we could tune both separately for the benchmark paper @jemus42 is working on.

The survival chapter needs a few updates, I should work on a revision/review I guess?

That would be great, thanks. I'm still trying to put together a docker container for the book build, and this chapter is currently the holdup.
