Changeset 2346 for LMDZ5/trunk/libf/phylmd/o3_chem_m.F90

Message:

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.
