Physics/dynamics separation:

  • remove all references to dimensions.h from physics. nbp_lon (==iim) , nbp_lat (==jjm+1) and nbp_lev (==llm) from mod_grid_phy_lmdz should be used instead.
  • added module regular_lonlat_mod in phy_common to store information about the global (lon-lat) grid cell boundaries and centers.
