[O] A possibly useful thing

[Tom Hinton]

Hi,

I made a thing, visible here:

  https://github.com/larkery/emacs/blob/master/site-lisp/org-numbers-overlay.el

Which adds overlays to headings in org-mode to display section numbering in the 
buffer, and keeps it up to date as you edit. This helps me when relating 
exported PDF output (or people's comments on it) back to the original org file.

Anyway it turns out it was helpful to some other people too, and one of them 
suggested that I contribute it directly and that to do so I should email this 
address, and now here we are.

Let me know if this fits into the org development master plan.

Thanks,

Tom Hinton
