Update some of the comments and the revision history.
Add support for reading in 4D temperature and extracting the surface layer.
Add a slightly more robust way of generating the fnames for the u and v wind data. Also put a try/catch in for the data dump so it will work with either uwnd/vwnd or u10/v10 struct fields.
Add support for Met Office Unified Model fields (or rather, for net surface fluxes rather than downward fluxes. Not sure if this is appropriate for FVCOM, but I will test it).
