Okay, so whenever I add an edge I need to assign it a unique index  
myself. Here's how I'm doing it for the initial construction of the  
graph:

size_t edgeIndex = 0;
for (...) {
    Vertex u = ...
    Vertex v = ...
    Edge edge;
    bool inserted;
    tie(edge, inserted) = add_edge(u, v, g);
    EdgeIndexMap edgeIndexMap = get(edge_index, g);
    put(edgeIndexMap, edge, edgeIndex++);
}

Does that look right? It seems to work, but I'm wondering if it's the  
best way.
