!==================================================================
!     
!     Purpose
!     -------
!     Run the physics package of the universal model in a 1D column.
!     
!     It can be compiled with a command like (e.g. for 25 layers):
!                                  "makegcm -p mars -d 25 testphys1d"
!     It requires the files "callphys.def", "z2sig.def",
!     "traceur.def", and "run1d.def" with a line "INCLUDEDEF=callphys.def"
!
!     Authors
!     -------
!     Frederic Hourdin
!     R. Fournier
!     F. Forget
!     F. Montmessin (water ice added)
