Simple wrappers around the new class-based generic views (introduced in Django 1.3) that also check permissions.

Example Usage (views.py):

from mymodule import RestrictedListView, RestrictedUpdateView

class MyListView(RestrictedListView):
    model = MyModel

class MyUpdateView(RestrictedUpdateView):
    model = MyModel

and so on for Create and Delete.
