Second section of namcouple for OUTPUT fields

The first 2 lines for fields with status OUTPUT are as follows:
  COSHFTOT  COSHFTOT   1   86400  0  fldhftot.nc OUTPUT 
  atmo   atmo
where the different entries are as for EXPOUT fields, except that: The name of the output file is automatically defined based on the field and component names.

The third line is LOCTRANS if this transformation is chosen for the field. Note that LOCTRANS is the only transformation supported for OUTPUT fields.
