Question: Add some links case studies to README.md.

[sgpinkus]

So I've read all the documentation and run through the tutorials. But I'm still not confident I can use this for anything practical, and the lack of activity on github and elsewhere tends to suggest there is a lack of uptake.

I'm now searching for case studies, but it would be good if you could make this easy for us, and sell the product a bit by linking to some from the README.md. For example http://flexible-energy.eu/portfolio-item/heerhugowaard/ (??).
