@savannahsakhai I think we can reserve the inclusion of saturation temperature and temperature-dependent diffusivity in a separate PR since we are prepping for a release and can get these straightforward changes in in the meantime.

Changes to comment clean up are good. Convert any feature requests to corresponding issues.
