Multiple object mixins

`MultipleObjectMixin`

class django.views.generic.list.MultipleObjectMixin

A mixin that can be used to display a list of objects.

If paginate_by is specified, Django will paginate the results returned by this. You can specify the page number in the URL in one of two ways:

Use the page parameter in the URLconf. For example, this is what your URLconf might look like:
```
url(r'^objects/page(?P<page>[0-9]+)/$', PaginatedView.as_view()),
```
Pass the page number via the page query-string parameter. For example, a URL would look like this:
```
/objects/?page=3
```
