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

- * 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.

-     * method chaining.
-     *
-     * In addition to Lo-Dash methods, wrappers also have the following `Array` methods:
-     * `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`, `splice`,
-     * and `unshift`
-     *
-     * Chaining is supported in custom builds as long as the `value` method is
-     * implicitly or explicitly included in the build.
-     *
-     * The chainable wrapper functions are:
-     * `after`, `assign`, `bind`, `bindAll`, `bindKey`, `chain`, `compact`,
-     * `compose`, `concat`, `countBy`, `create`, `createCallback`, `curry`,
-     * `debounce`, `defaults`, `defer`, `delay`, `difference`, `filter`, `flatten`,
-     * `forEach`, `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`,
-     * `functions`, `groupBy`, `indexBy`, `initial`, `intersection`, `invert`,
-     * `invoke`, `keys`, `map`, `max`, `memoize`, `merge`, `min`, `object`, `omit`,
-     * `once`, `pairs`, `partial`, `partialRight`, `pick`, `pluck`, `pull`, `push`,
-     * `range`, `reject`, `remove`, `rest`, `reverse`, `shuffle`, `slice`, `sort`,
-     * `sortBy`, `splice`, `tap`, `throttle`, `times`, `toArray`, `transform`,
-     * `union`, `uniq`, `unshift`, `unzip`, `values`, `where`, `without`, `wrap`,
-     * and `zip`
-     *
-     * The non-chainable wrapper functions are:
-     * `clone`, `cloneDeep`, `contains`, `escape`, `every`, `find`, `findIndex`,
-     * `findKey`, `findLast`, `findLastIndex`, `findLastKey`, `has`, `identity`,
-     * `indexOf`, `isArguments`, `isArray`, `isBoolean`, `isDate`, `isElement`,
-     * `isEmpty`, `isEqual`, `isFinite`, `isFunction`, `isNaN`, `isNull`, `isNumber`,

-     * `reduceRight`, `result`, `shift`, `size`, `some`, `sortedIndex`, `runInContext`,
-     * `template`, `unescape`, `uniqueId`, and `value`
