* Add 'flag_in_output' keyword to the list of possible keywords in a GEOGRID.TBL.
* Add code to pass through flags in the geogrid output files to the
metgrid output files; n.b. that this only works correctly if the name
of the flag is FLAG_fieldname, where fieldname is the name of a field in
the geogrid output file.
* BONUS BUG FIX: deallocate is_subgrid array in source_data_module.F.
