Routers provide a convenient and consistent way of automatically
determining the URL conf for your API.

They are used by simply instantiating a Router class, and then registering
all the required ViewSets with that router.

For example, you might have a `urls.py` that looks something like this:

    router = routers.DefaultRouter()
    router.register('users', UserViewSet, 'user')
    router.register('accounts', AccountViewSet, 'account')

    urlpatterns = router.urls

        Given a viewset, return the portion of URL regex that is used
        to match against a single instance.

        Note that lookup_prefix is not used directly inside REST rest_framework
        itself, but is required in order to nicely support nested router
        implementations, such as drf-nested-routers.
