Allows access to nodes to be determined by a field set on the content.
This is currently hard-coded to utilize a field named
field_associated_users, which must be a an entity reference field to user entities. Content types with this field will only be viewable by users referenced by the field, or users with the
bypass node access permission.
Content types without the
field_associated_users field will be subject to default Drupal node access handling via permissions.
