In summary, with the release of django 1.8 all the formtools logic was moved to a separate repo.  The question is, how does a 3rd party app that requires formtools setup the install_requires portion of the setup.py file to work for both django < 1.8 and django >= 1.8 when the django-formtools app requires django version >= 1.7 which will cause conflicts with users using django < 1.7 on install?
