    model from the atmospheric and boundary forcing, we can use a restart
    file to cheat. For this, we need temperature and salinity
    (potentially other variables too) interpolated onto the unstructured
    grid. The interpolated data can then be written out with
    write_FVCOM_restart.m.

 INPUT:
   Mobj        = MATLAB mesh structure which must contain:
                   - Mobj.lon, Mobj.lat and/or Mobj.lonc, Mobj.latc - node
                   or element centre coordinates (long/lat). D
