FR: A helper function for the reference index that will catch all not otherwise captured.

[Moohan]

It would be great to have a helper function e.g. everything() which could be used as a catch-all for anything not otherwise captured by the reference index. At present, it throws a warning (or error in an action) if a function is missing from the reference. I would ideally have a yml as follows.

url: ~
template:
  bootstrap: 5

reference:
  - title: Some functions
    desc: Functions which do `a`
  - contents:
    - starts_with("do_a")
 
  - title: Some other functions
    desc: Functions which do `b` 
  - contents:
    - starts_with("do_b")

  - title: Everything else
  - desc: Functions which don't fall into the other categories
  - contents:
    - everything()
