Errors unless logged in

You get errors unless you're logged in. Without an auth app, that likely means from the admin. I think it's worth mentioning in the README.

Ah, you're right. I added the login_required decorator to all the CreateView, UpdateView, and DeleteView classes because I've never personally built an app where you could create, update or delete without being logged in. But I can definitely imagine scenarios where that would be the case. I think ideally I'd make this decorator optional. Until then, I've updated the README per your recommendation.
