Mars PEM:
Introduction of the possibility to follow an orbital forcing.
Introduction of new control parameters.
Cleaning of the PEM (removing unused files, add comments and new files)

A file named run_PEM.def can be added to the run.def. It contains the following variables:

_ evol_orbit_pem: Boolean. Do you want to follow an orbital forcing predefined (read in ob_ex_lsp.asc for example)? (default=false)
_ year_bp_ini: Integer. Number of year before present to start the pem run if evol_orbit_pem=.true. , default=0
_ Max_iter_pem: Integer. Maximal number of iteration if none of the stopping criterion is reached and if evol_orbit_pem=.false., default=99999999
_ dt_pem: Integer. Time step of the PEM in year, default=1
_ alpha_criterion: Real. Acceptance rate of sublimating ice surface change, default=0.2
_ soil_pem: Boolean. Do you want to run with subsurface physical processes in the PEM? default=.true.
