New chapter: Case study

This is the biggest chapter so far, with lots of diagrams and about 20 pages of text. I cheated a little bit, as I have finished the chapter by hiding two sub-sections that I may or may not come back and complete. If you do read the chapter, let me know what is missing or what could be improved with another example.

The whole book can be found in the usual place.

Doh, I wrote this blog post yesterday but never pressed “submit”.
