can be used to create exterior property maps for the capacity and flow properties, which are stored in arrays. The arrays are
indexed by edge ID. The edge ID is added to the graph using a property,
and the values of the ID's are given when each edge is added to the
graph. The complete source code for this example is in
<TT>example/exterior_edge_properties.cpp</TT>. The
<TT>print_network()</TT> function prints out the graph with
the flow and capacity values.
