-------- DESCRIPTION ---------------------------------------------------------

This module allows different access permissions to be given to authors, referenced users and non-referenced users.

When an author has created content containing a user reference field (with author update/delete grants enabled) and the author's user account is later deleted, content created by them can be edited by anonymous users.
