Hello,

I am wondering if there is not a documentation bug.

The distance_recorder<DistanceMap, EventTag> manual page states:

   DistanceMap 	A WritablePropertyMap, where the key type and the value type are the vertex descriptor type of the graph.

Shouldn't the value type be something like int. After all it is a distance
measured in the number of hops in the graph.

Also writing my own DistanceMap I had to also provide the function   get
in order that it compiles. So the DistanceMap should  be Readable as well.
