 file.

 function write_FVCOM_z0(z0, filename, mytitle)

 DESCRIPTION:
    Generate a NetCDF file containing spatially variable z0 for FVCOM

 INPUT
   z0        = user defined roughness field (m)
               roughness is defined on the elements
               expect values between 3 10^-3 (gravel) and .2 10^-3 (i.e. 0.0002) for mud
