simple test suite enabling Django app testing via setup.py (Python3 version)

 Django Setuptest is a simple module enabling Django app testing via setup.py.
 .
 Normally when you execute
 .
  $ python setup.py test
 .
 for Django related modules you're almost certain to run into
 DJANGO_SETTINGS_MODULE environment variable issues, e.g.:
 .
     ImportError: Settings cannot be imported, because environment variable
     DJANGO_SETTINGS_MODULE is undefined.
 .
 This module overcomes this by configuring the DJANGO_SETTINGS_MODULE
 environment variable before executing your test suite. As a bonus it also
 generates Coverage and PEP 8 reports as part of the test.
 .
 This is the Python 3 version of the package.
