Locations and References for Emacs

If there is a string like "[[ref:1234]]" in some buffer, then this minor mode
will turn it into a "Reference". A reference may be viewed as a button such that a
click will search for the matching "Location" in files' content, file names and
buffers. A matching location may be a string "[[id:1234]]" or a file named "1234".

More precisely:

- A location is defined as:
  - or :ID: <ID>
  - or [[id:<ID>]]
  - or [[id:<ID>][<name>]]

- A reference is defined as:
  - or :REF: <ID>
  - or [[ref:<ID>]]
  - or [[ref:<ID>][<name>]]

This package requires 'ripgrep' and 'fd' to be installed on your system for full
functionality.

- Ripgrep: For fast text search.
- fd: For fast file search.
