-/*
- * 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.

- * Creates a `lodash` object which wraps `value` to enable implicit chaining.
- * Methods that operate on and return arrays, collections, and functions can
- * be chained together. Methods that retrieve a single value or may return a
- * primitive value will automatically end the chain returning the unwrapped
- * value. Explicit chaining may be enabled using `_.chain`. The execution of
- * chained methods is lazy, that is, execution is deferred until `_#value`
- * is implicitly or explicitly called.
- *
- * Lazy evaluation allows several methods to support shortcut fusion. Shortcut
- * fusion is an optimization strategy which merge iteratee calls; this can help
- * to avoid the creation of intermediate data structures and greatly reduce the
- * number of iteratee executions.
- *
- * Chaining is supported in custom builds as long as the `_#value` method is
- * directly or indirectly included in the build.
- *
- * In addition to lodash methods, wrappers have `Array` and `String` methods.
- *
- * The wrapper `Array` methods are:
- * `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`,
- * `splice`, and `unshift`
- *
- * The wrapper `String` methods are:
- * `replace` and `split`
- *
- * The wrapper methods that support shortcut fusion are:
- * `compact`, `drop`, `dropRight`, `dropRightWhile`, `dropWhile`, `filter`,
- * `first`, `initial`, `last`, `map`, `pluck`, `reject`, `rest`, `reverse`,
- * `slice`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `toArray`,
- * and `where`
- *
- * The chainable wrapper methods are:
- * `after`, `ary`, `assign`, `at`, `before`, `bind`, `bindAll`, `bindKey`,
- * `callback`, `chain`, `chunk`, `commit`, `compact`, `concat`, `constant`,
- * `countBy`, `create`, `curry`, `debounce`, `defaults`, `defaultsDeep`,
- * `defer`, `delay`, `difference`, `drop`, `dropRight`, `dropRightWhile`,
- * `dropWhile`, `fill`, `filter`, `flatten`, `flattenDeep`, `flow`, `flowRight`,
- * `forEach`, `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`,
- * `functions`, `groupBy`, `indexBy`, `initial`, `intersection`, `invert`,
- * `invoke`, `keys`, `keysIn`, `map`, `mapKeys`, `mapValues`, `matches`,
- * `matchesProperty`, `memoize`, `merge`, `method`, `methodOf`, `mixin`,
- * `modArgs`, `negate`, `omit`, `once`, `pairs`, `partial`, `partialRight`,
- * `partition`, `pick`, `plant`, `pluck`, `property`, `propertyOf`, `pull`,
- * `pullAt`, `push`, `range`, `rearg`, `reject`, `remove`, `rest`, `restParam`,
- * `reverse`, `set`, `shuffle`, `slice`, `sort`, `sortBy`, `sortByAll`,
- * `sortByOrder`, `splice`, `spread`, `take`, `takeRight`, `takeRightWhile`,
- * `takeWhile`, `tap`, `throttle`, `thru`, `times`, `toArray`, `toPlainObject`,
- * `transform`, `union`, `uniq`, `unshift`, `unzip`, `unzipWith`, `values`,
- * `valuesIn`, `where`, `without`, `wrap`, `xor`, `zip`, `zipObject`, `zipWith`
- *
- * The wrapper methods that are **not** chainable by default are:
- * `add`, `attempt`, `camelCase`, `capitalize`, `ceil`, `clone`, `cloneDeep`,
- * `deburr`, `endsWith`, `escape`, `escapeRegExp`, `every`, `find`, `findIndex`,
- * `findKey`, `findLast`, `findLastIndex`, `findLastKey`, `findWhere`, `first`,
- * `floor`, `get`, `gt`, `gte`, `has`, `identity`, `includes`, `indexOf`,
- * `inRange`, `isArguments`, `isArray`, `isBoolean`, `isDate`, `isElement`,
- * `isEmpty`, `isEqual`, `isError`, `isFinite` `isFunction`, `isMatch`,
- * `isNative`, `isNaN`, `isNull`, `isNumber`, `isObject`, `isPlainObject`,
- * `isRegExp`, `isString`, `isUndefined`, `isTypedArray`, `join`, `kebabCase`,
- * `last`, `lastIndexOf`, `lt`, `lte`, `max`, `min`, `noConflict`, `noop`,
- * `now`, `pad`, `padLeft`, `padRight`, `parseInt`, `pop`, `random`, `reduce`,

- Implementation Summary
-
- 1. Enforce API surface and semantic compatibility with 1.9.x branch
- 2. Improve the module's maintainability by reducing the storage
- paths to a single mechanism.
- 3. Use the same single mechanism to support "private" and "user" data.
- 4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
- 5. Avoid exposing implementation details on user objects (eg. expando properties)
- 6. Provide a clear path for implementation upgrade to WeakMap in 2014
