This allows you to add permissions for anonymous, logged in user, author ... in the url:
-By default `LDPPermissions` is used.
-Specific permissin classes can be developed to fit special needs.
-
-## anonymous_perms, user_perms, owner_perms, superuser_perms
-
-Those allow you to set permissions from your model's meta.
-
-You can give the following permission to them:
-
-* `view`
-* `add`
-* `change`
-* `control`
-* `delete`
-* `inherit`
-
-With inherit, Users can herit from Anons. Also Owners can herit from Users.
-
-Eg. with this model Anons can view, Auths can add & Owners can edit & delete.
-
-Note that `owner_perms` need a `owner_field` or a `owner_urlid_field` meta that point the field with owner user.
