Mars GCM:
Series of changes to enable running in parallel (using LMDZ.COMMON dynamics);
Current LMDZ.MARS can still notheless be compiled and run in serial mode
"as previously".
Summary of main changes:

• Main programs (newstart, start2archive, xvik) that used to be in dyn3d have been moved to phymars.
• dyn3d/control.h is now module control_mod.F90
• rearanged input/outputs routines everywhere to handle serial/MPI cases. physdem.F => phyredem.F90 , phyetat0.F => phyetat0.F90 ; all read/write routines for startfi files are gathered in module iostart.F90
• added parallelism related routines init_phys_lmdz.F90, comgeomphy.F90, dimphy.F90, iniphysiq.F90, mod_grid_phy_lmdz.F90, mod_phys_lmdz_mpi_data.F90, mod_phys_lmdz_mpi_transfert.F90, mod_phys_lmdz_omp_data.F90, mod_phys_lmdz_omp_transfert.F90, mod_phys_lmdz_para.F90, mod_phys_lmdz_transfert_para.F90 in phymars and mod_const_mpi.F90 in dyn3d (for compliance with parallel case)
• created generic routines 'planetwide_maxval' and 'planetwide_minval', in module "planetwide_mod", that enable obtaining the min and max of a field over the whole planet.
