This one overwhelms github with the number of new files, but will take it on faith.

Thanks @lgannoaa for merging your changes! Did you test them with the dev-sci branch or the production/RRFS.v1 branch? I see some variables in exrrfs_fsm.sh which have been renamed in the production/RRFS.v1 branch, such as NWGES_BASEDIR (NWGES) and fcst_fv3lam (forecast). So I think those variable names will have to be updated to be able to run in the production/RRFS.v1 branch. I took a half day on Friday so didn't get a chance to comment on this PR before it was merged.
