Re #2077 review.

• Minor docstring reviews
• Minimal MultiPhysicsMedium silicon library.
• Silicon example default everywhere.
• Debugged weird R parameter bug?

Thanks @daquinteroflex for being on top of this. I'll finish the rest of the comments on Monday, when I'll probably have Daniil's feedback

For the material library situation default, there are many combinations of a given Si SemiconductorMedium. This is due to the many recombination models, etc. There's one that makes most sense. I'm only going to create one combination of a MultiPhysicsMedium(charge=SemiconductorMedium(our single instantiated parameters)) in order to have a minimal instantiation, and the remaining silicon defaults I will make them a docstring example on each class since that way people can simply create the higher level models they want from them. They will have to read the docs to determine the corresponding defaults. Fyi @dbochkov-flexcompute

looks great!

Sorry this is getting nit-picky but some of the docstrings still sound unnecessarily verbose to me :)

Thanks everyone for your comments. I have addressed all of them.

I will merge this branch. Any additional comments can be dealt with in #2077
