* Cascading Checkbox Cookie Counts
  I would like checkbox cookies to show the total of all cookies beneath
them regardless of hierarchy nesting.
  The code for ~org-update-checkbox-count~ is more complex than I expected
so before spending time digging into this, maybe someone here has a tip?

** This should show 3/5 [1/2]
   - [X] Done
   - [ ] Not Done
** Nesting level 1
   - [ ] Not Done
   - [X] Done
** Nesting level 2
*** Nesting level 2.1
    - [X] Done

** Cookie data recursive doesn't seem to affect this
   My understanding is that there's a cookie data ~<recursive>~ property
flag you can use. I assumed that's what this was for but it seems to not
affect things (I've tried both with and without the angle braces, but the
regex seems to imply braces which is odd)
*** This should show 3/5 [1/2]
    :PROPERTIES:
    :COOKIE_DATA: <recursive>
    :END:
