Mars GCM:
dyn3dpar: Implementation in the parallel version of the dynamics of the dynamical transport of the isotopes using the same scheme as the one
implemented by Camille Risi in the Earth GCM (see LMDZ6/libf/dyn3dmem, and Risi et al. 2009: genealogy of the tracers+transport of the isotopic
ratio). This is added to prepare the future implementation of the HDO cycle in the GCM. These changes had been already added in the sequential part.
dyn3d: corrections to prevent from dividing by zero in the case of the use of the isotopes scheme.
traceur.def.isotopes: example of how to write the traceur.def if you want to use the new dynamics with the genealogy of the isotopes: air is the
father of all, H2O is the father of HDO.
