 ### Changed

+-Changed Chem_SettlingSimple in the process library to call Mie Query for radius and rhop inputs to the settling velocity calculation. The calls to Chem_SettlingSimple were then changed accordingly in each of the species' grid comps. Since the RH flag is no longer needed, it was removed from GA_EnvironmentMod.F90 and each of the instance RC files.
