+ * The network simplex algorithm assigns ranks to each node in the input graph

+ *
+ *
+ * A rough sketch of the algorithm is as follows:
+ *
+ *    1. Assign initial ranks to each node. We use the longest path algorithm,
+ *       which assigns ranks to the lowest position possible. In general this
+ *       leads to very wide bottom ranks and unnecessarily long edges.

+ *       edges in the tree have no slack (difference between length of edge
+ *       and minlen for the edge). This by itself greatly improves the assigned
+ *       rankings by shorting edges.
+ *    3. Iteratively find edges that have negative cut values. Generally a
+ *       negative cut value indicates that the edge could be removed and a new
