1. Adding initial subroutine calc_ice_cloud_frac_component. (details)
2. Cleaning up new subroutine calc_liquid_cloud_frac_component, and making sat_mixrat_ice a subroutine that works the same way as sat_mixrat_liq. larson-group/clubb#972 (details)
3. Comment update (details)
4. Removing these paratheses is BIT_CHANGING since it modifies the order of operations, but allows for the multiplication and subraction to be done in parallel for complex pipelines. (details)
