Description

This adds an out of band example of how to use django-sockpuppet. It's worth noting that the redis channel layer is a requirement for this to work (besides, redis should always be used in a production environment).

To test this out

• Fork the library
• Install all requirements_dev.txt
• Make sure you are using the redis channel layers
• run python manage.py runserver
• run npm run build:watch
• go to http://localhost:8000/progress
• run python manage.py progressbar
• behold the progressbar being filled each second.

Why should this be added

I was asked for an example :)
