I'd accumulated a few things to make my life easier when editing MESA
inlists with emacs. I got around to tidying them up, bundling it all
together, and adding a little documentation. It's no masterwork, but
I thought others might find it useful, so I figured I'd share it.
Basically, it just makes using some existing emacs features easier,
like jumping to/from MESA documentation with tags,
commenting/uncommenting regions and toggling boolean values.
