use graph_traits whenver possible #8

We have two ways of getting graph attributes in the tutorial. For example, vertex_descriptor

using vd = typename graph::vertex_descriptor;

using vd = typename boost::graph_traits<graph>::vertex_descriptor;

The difference is graph_traits is able to store type information externally, and it's easy to customize it by template partial specialization.

Sounds like a great suggestion. Feel encouraged to change code to use graph_traits :+1:
