-     * 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`,

-     * `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`,

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

- *    2. All nodes in the graph must have an object value.
- *    3. All edges in the graph must have "minlen" and "weight" attributes.

- *       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

-     * Creates a `lodash` object which wraps `value` to enable implicit method
-     * chain sequences. 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 sequence
-     * and return the unwrapped value. Otherwise, the value must be unwrapped
-     * with `_#value`.
-     *
-     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
-     * enabled using `_.chain`.
-     *
-     * The execution of chained methods is lazy, that is, it's deferred until
-     * `_#value` is implicitly or explicitly called.
-     *
-     * Lazy evaluation allows several methods to support shortcut fusion.
-     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-     * the creation of intermediate arrays and can greatly reduce the number of
-     * iteratee executions. Sections of a chain sequence qualify for shortcut
-     * fusion if the section is applied to an array of at least `200` elements
-     * and any iteratees accept only one argument. The heuristic for whether a
-     * section qualifies for shortcut fusion is subject to change.
-     *
-     * Chaining is supported in custom builds as long as the `_#value` method is
-     * directly or indirectly included in the build.
-     *

-  the parseError function receives a 'hash' object with these members for lexer and parser errors: {

-    token:       (the produced terminal token, if any)
-    line:        (yylineno)

-  while parser (grammar) errors will also provide these members, i.e. parser errors deliver a superset of attributes: {
-    loc:         (yylloc)
-    expected:    (string describing the set of expected tokens)
-    recoverable: (boolean: TRUE when the parser has a error recovery rule available for this particular error)
