Add new function to write out a WRF format netCDF file. This can be used instead of an interpolated FVCOM format file because FVCOM will do a biliniear interpolation of the WRF file supplied. This makes generating the surface forcing a lot faster. This function is in part based on a similar function (dump_meteo_fvgrid) written by Dmitry Aleynik at SAMS.
Function to read in the converted Met Office Unified Model (TM) files (see pp2nc.m).
