tutorial sanity check

[Anil Madhavapeddy <anil@xxxxxxxxxx>]

In case anyone else has time (Balraj, Raphael mainly), I've pushed a 99% 
version of the tutorial to avsm/mirage-tutorial.git; just cd slides && make and 
it will listen on localhost:8000

It is pretty self-contained (but 80+ slides!), and could use a quick sanity run 
through the examples to make sure they work for you. There are skeleton 
versions of the files in mirage-tutorial/examples. 

Some of the early diagrams are quite poor, so I'll be fleshing those out 
tomorrow morning and adding more ending content (once I get the EC2 scripts 
working again ;)

Any comments most welcome in the next few hour!
