>> How are weighted edgelist files defined and used?

A weighted edgelist has the following format:
node1 id    node2 id    edgeweight1
nodeX id    nodeY id    edgeweight2
nodeY id    nodeZ id    edgeweight3

The EdgeListReader automatically detects if the graph is weighted (3 
values per line) or not (2 values per line). The EdgeListReader cannot 
know if a graph is directed, therefore, the parameter directed is used 
for. I think that's all there is to it.
