// This tests the following behaviour:
// 1. A namespace should not be editable if it is archived.
//   1. With the exception being to un-archive it.
// 2. A list which belongs to an archived namespace cannot be edited.
// 3. An archived list should not be editable.
//   1. Except for un-archiving it.
// 4. It is not possible to un-archive a list individually if its namespace is archived.
// 5. Creating new lists on an archived namespace should not work.
// 6. Creating new tasks on an archived list should not work.
// 7. Creating new tasks on a list who's namespace is archived should not work.
// 8. Editing tasks on an archived list should not work.
// 9. Editing tasks on a list who's namespace is archived should not work.
// 10. Archived namespaces should not appear in the list with all namespaces.
// 11. Archived lists should not appear in the list with all lists.
// 12. Lists who's namespace is archived should not appear in the list with all lists.
//
// All of this is tested through integration tests because it's not yet clear if this will be implemented directly
// or with some kind of middleware.
//
// Maybe the inheritance of lists from namespaces could be solved with some kind of is_archived_inherited flag -
// that way I'd only need to implement the checking on a list level and update the flag for all lists once the
// namespace is archived. The archived flag would then be used to not accedentially unarchive lists which were
// already individually archived when the namespace was archived.
// Should still test it all though.
//
// Namespace 16 is archived
// List 21 belongs to namespace 16
// List 22 is archived individually
