Title: Explicitly use vertex type on quick tour example.

It is better to explicitly use types on the tutorial so that new users know what types are returned.

I am learning the interface now and this is the first question that came to my mind when reading this, and I had to search a bit for the answer.

BTW, this Git repo is the official place to contribute to Boost Graph is that it?
