[MITgcm-support] external forcing

[Dimitris Menemenlis]

Dmitri, "with" USE_EXF_INTERPOLATION, you can use any type of grid, including 
hand-made curvilinear, as long as the grid has associated latitude/longitude 
coordinates.  The only thing that does not work, right now, with 
USE_EXF_INTERPOLATION is Cartesian grids that have no latitude/longitude 
information associated with them, although I suspect that fix to make this work 
would be trivial.  Cheers, Dimitris
