conf_phys.F @ 1944

Last change on this file since 1944 was 1918, checked in by emillour, 7 years ago

Mars GCM:
Code cleanup:

remove "comorbit.h" since it is no longer used.
turn "datafile.h" into module datafile_mod.F90 (and rename variable "datafile" as "datadir" since it stores the path to the datafile directory).
