Detailed Description

The arithmetic of interpolating forcing from a rectilinear lat-lon grid onto REMORA's rho points and rotating vectors onto the grid axes (LatLonRegrid, REMORA::rotate_to_grid_axes), kept free of MultiFabs and NetCDF so that Tests/Unit can check it directly. Nothing here depends on REMORA_USE_NETCDF.
