f property values, and the length of the range must be the
number of vertices or edges in the graph (depending on whether it is a
vertex or edge property map). The adaptor must also be supplied
with an ID property map, which will be used to map the vertex or
edge descriptor to the offset of the property value (offset from the
random access iterator). The ID property map will typically be an
interior property map of the graph.  The following example shows
how the <TT>random_access_iterator_property_map</TT>
