           * The network simplex algorithm assigns ranks to each node in the input graph
           * and iteratively improves the ranking to reduce the length of edges.
           *
           * Preconditions:
           *
           *    1. The input graph must be a DAG.
           *    2. All nodes in the graph must have an object value.
           *    3. All edges in the graph must have "minlen" and "weight" attributes.
           *
           * Postconditions:
           *
           *    1. All nodes in the graph will have an assigned "rank" attribute that has
           *       been optimized by the network simplex algorithm. Ranks start at 0.
           *
           *
           * 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.
           *    2. Construct a feasible tight tree. A tight tree is one such that all
           *       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
           *       tree edge could be added to produce a more compact graph.
           *
           * Much of the algorithms here are derived from Gansner, et al., "A Technique
           * for Drawing Directed Graphs." The structure of the file roughly follows the
           * structure of the overall algorithm.
