Converting from Graph to Boost::Graph

• vertices() becomes get_nodes()
• out_degree() becomes children_of_directed()
• in_degree() becomes parents_of_directed()
• neighbors() returns an arrayref instead of an array (watch out for that American speeling)

Improvements for documentation

The functions are a little light on what they actually do to someone who is coming to the module for the first time.

• explain in graph terminology (not always consistent) what the children/parents are
