   statement semantics: children have a list of submodules belonging to a
   package, and ignore requests for submodules that did not exist on the master.
 
-* Imports are extracted from each module, compared to those found in memory,
-  and recursively preloaded into children requesting that module, minimizing
-  round-trips to one per package nesting level. For example,
-  :py:mod:`django.db.models` only requires 3 round-trips to transfer 456KiB,

-Class-based views
-    1. Add an import:  from other_app.views import Home
-    2. Add a URL to urlpatterns:  url(r'^$', Home.as_view(), name='home')
-Including another URLconf
-    1. Import the include() function: from django.conf.urls import url, include
-    2. Add a URL to urlpatterns:  url(r'^blog/', include('blog.urls'))
