o Added on-the-fly spatial interpolation capability
    "USE_EXF_INTERPOLATION" to pkg/exf.
  - This is a temporary Cartesian-grid hack until
    the super-duper ESMF coupler becomes available.
  - See verification/global_with_exf/README for usage example.
  - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
    flags and modified pkg/seaice accordingly.
o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
    and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
    non-local transport term.

51     C
52 dimitri 1.7 C All surface forcing fields are defined at the center of
53     C each grid (the rVel location in model/inc/GRID.h).
54     C
55 dimitri 1.5 C #ifdef SEAICE_EXTERNAL_FORCING, sea-ice forcing fields
56     C are defined in exf_fields.h
57     C
58     C #ifdef SEAICE_EXTERNAL_FLUXES, additional forcing fields, fu,
59     C fv, Qnet, Qsw, and EmPmR, as defined in FFIELDS.h, are required.
60     C
61     C Downward and net radiative fluxes are not the same !!!
62     C Downward radiative fluxes, swdown and lwdown, are used by
63     C radiation bulk formulae to compute net radiative fluxes.
