PEM:
Big cleaning/improvements of the PEM:

  • Conversion of "abort_pem.F" and "soil_settings_PEM.F" into Fortran 90;
  • Transformation of every PEM subroutines into module;
  • Rewriting of many subroutines with modern Fortran syntax;
  • Correction of a bug in "pem.F90" when calling 'recomp_tend_co2_slope'. The arguments were given in disorder and emissivity was missing;
  • Update of "launch_pem.sh" in deftank.
