The LvaluePropertyMap interface returns a reference to the stored value.
Anotherwords, instead of using get() use operator[].

Hmm, looking at the adjacency_list documentation, it says that it's
property maps only support Readable and ReadWrite. This is a mistake. They
support LvaluePropertyMap. I'll fix the docs.
