This module collects helper functions and classes that "span" multiple levels
of MVC. In other words, these functions/classes introduce controlled coupling
for convenience's sake.

    Return an HttpResponseRedirect to the appropriate URL for the arguments
    passed.

    The arguments could be:

        * A model: the model's `get_absolute_url()` function will be called.

        * A view name, possibly with arguments: `urls.reverse()` will be used
          to reverse-resolve the name.

        * A URL, which will be used as-is for the redirect location.

    Issues a temporary redirect by default; pass permanent=True to issue a
    permanent redirect.

    Return a QuerySet or a Manager.
    Duck typing in action: any class with a `get()` method (for
    get_object_or_404) or a `filter()` method (for get_list_or_404) might do
    the job.

    Use get() to return an object, or raise an Http404 exception if the object
    does not exist.

    klass may be a Model, Manager, or QuerySet object. All other passed
    arguments and keyword arguments are used in the get() query.

    Like with QuerySet.get(), MultipleObjectsReturned is raised if more than
    one object is found.
