A more robust way to refer to gas type.

  • Gas names with an arbitrary number of characters (<20) can be used This is good for C2H2, C2H6, H2SO4, C17H21NO4, etc... !!! Remember this must be compliant with Q.dat in corrk_data !!!
  • igas_... labels are assigned once for all in su_gases Then using igas_... everywhere instead of gnom (except for kcm stuff)
  • Users can still use e.g. H2_ but H2 also works
  • Simplified condense_cloud so that igas_CO2 is used directly
  • Property svn:executable set to *
