[Users] Adding gridfunction output mid-subroutine?

[Scott Hawley]

Hey guys,
  Frank recommended CCTK_OutputVarAsByMethod, but gave code for
CCTK_OutputVarAsBy.
When I use the latter, the code segmentation faults.

Ian, I couldn't find where you set the variable output_method in your
example.  Where does that definition go?

  CCTK_OutputVarAsByMethod(cctkGH, fullvarname, output_method, alias_name);


Thanks,
Scott
