/**
  `Promise.all` accepts an array of promises, and returns a new promise which
  is fulfilled with an array of fulfillment values for the passed promises, or
  rejected with the reason of the first passed promise to be rejected. It casts all
  elements of the passed iterable to promises as it runs this algorithm.

  Example:

  ```javascript
  let promise1 = resolve(1);
  let promise2 = resolve(2);
  let promise3 = resolve(3);
  let promises = [ promise1, promise2, promise3 ];

  Promise.all(promises).then(function(array){
    // The array here would be [ 1, 2, 3 ];
  });
  ```

  If any of the `promises` given to `all` are rejected, the first promise
  that is rejected will be given as an argument to the returned promises's
  rejection handler. For example:

  Example:

  ```javascript
  let promise1 = resolve(1);
  let promise2 = reject(new Error("2"));
  let promise3 = reject(new Error("3"));
  let promises = [ promise1, promise2, promise3 ];

  Promise.all(promises).then(function(array){
    // Code here never runs because there are rejected promises!
  }, function(error) {
    // error.message === "2"
  });
  ```

  @method all
  @static
  @param {Array} entries array of promises
  @param {String} label optional string for labeling the promise.
  Useful for tooling.
  @return {Promise} promise that is fulfilled when all `promises` have been
  fulfilled, or rejected if any of them become rejected.
  @static
*/
function all(entries) {
  return new Enumerator(this, entries).promise;

/**
  `Promise.race` returns a new promise which is settled in the same way as the
  first passed promise to settle.

  Example:

  ```javascript
  let promise1 = new Promise(function(resolve, reject){
    setTimeout(function(){
      resolve('promise 1');
    }, 200);
  });

  let promise2 = new Promise(function(resolve, reject){
    setTimeout(function(){
      resolve('promise 2');
    }, 100);
  });

  Promise.race([promise1, promise2]).then(function(result){
    // result === 'promise 2' because it was resolved before promise1
    // was resolved.
  });
  ```

  `Promise.race` is deterministic in that only the state of the first
  settled promise matters. For example, even if other promises given to the
  `promises` array argument are resolved, but the first settled promise has
  become rejected before the other promises became fulfilled, the returned
  promise will become rejected:

  ```javascript
  let promise1 = new Promise(function(resolve, reject){
    setTimeout(function(){
      resolve('promise 1');
    }, 200);
  });

  let promise2 = new Promise(function(resolve, reject){
    setTimeout(function(){
      reject(new Error('promise 2'));
    }, 100);
  });

  Promise.race([promise1, promise2]).then(function(result){
    // Code here never runs
  }, function(reason){
    // reason.message === 'promise 2' because promise 2 became rejected before
    // promise 1 became fulfilled
  });
  ```

  An example real-world use case is implementing timeouts:

  ```javascript
  Promise.race([ajax('foo.json'), timeout(5000)])
  ```

  @method race
  @static
  @param {Array} promises array of promises to observe

/**
  Promise objects represent the eventual result of an asynchronous operation. The
  primary way of interacting with a promise is through its `then` method, which
  registers callbacks to receive either a promise's eventual value or the reason
  why the promise cannot be fulfilled.

  Terminology
  -----------

  - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
  - `thenable` is an object or function that defines a `then` method.
  - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
  - `exception` is a value that is thrown using the throw statement.
  - `reason` is a value that indicates why a promise was rejected.
  - `settled` the final resting state of a promise, fulfilled or rejected.

  A promise can be in one of three states: pending, fulfilled, or rejected.

  Promises that are fulfilled have a fulfillment value and are in the fulfilled
  state.  Promises that are rejected have a rejection reason and are in the
  rejected state.  A fulfillment value is never a thenable.

  Promises can also be said to *resolve* a value.  If this value is also a
  promise, then the original promise's settled state will match the value's
  settled state.  So a promise that *resolves* a promise that rejects will
  itself reject, and a promise that *resolves* a promise that fulfills will
  itself fulfill.


  Basic Usage:
  ------------

  ```js
  let promise = new Promise(function(resolve, reject) {
    // on success
    resolve(value);

    // on failure
    reject(reason);
  });

  promise.then(function(value) {
    // on fulfillment
  }, function(reason) {
    // on rejection
  });
  ```

  Advanced Usage:
  ---------------

  Promises shine when abstracting away asynchronous interactions such as
  `XMLHttpRequest`s.

  ```js
  function getJSON(url) {
    return new Promise(function(resolve, reject){
      let xhr = new XMLHttpRequest();

      xhr.open('GET', url);
      xhr.onreadystatechange = handler;
      xhr.responseType = 'json';
      xhr.setRequestHeader('Accept', 'application/json');
      xhr.send();

      function handler() {
        if (this.readyState === this.DONE) {
          if (this.status === 200) {
            resolve(this.response);
          } else {
            reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
          }
        }
      };
    });
  }

  getJSON('/posts.json').then(function(json) {
    // on fulfillment
  }, function(reason) {
    // on rejection
  });
  ```

  Unlike callbacks, promises are great composable primitives.

  ```js
  Promise.all([
    getJSON('/posts'),
    getJSON('/comments')
  ]).then(function(values){
    values[0] // => postsJSON
    values[1] // => commentsJSON

    return values;
  });
  ```

  @class Promise
  @param {Function} resolver
  Useful for tooling.
  @constructor
*/

var Promise$1 = function () {
  function Promise(resolver) {
    this[PROMISE_ID] = nextId();
    this._result = this._state = undefined;
    this._subscribers = [];

    if (noop !== resolver) {
      typeof resolver !== 'function' && needsResolver();
      this instanceof Promise ? initializePromise(this, resolver) : needsNew();
    }
  }

  /**
  The primary way of interacting with a promise is through its `then` method,
  which registers callbacks to receive either a promise's eventual value or the
  reason why the promise cannot be fulfilled.
   ```js
  findUser().then(function(user){
    // user is available
  }, function(reason){
    // user is unavailable, and you are given the reason why
  });
  ```
   Chaining
  --------
   The return value of `then` is itself a promise.  This second, 'downstream'
  promise is resolved with the return value of the first promise's fulfillment
  or rejection handler, or rejected if the handler throws an exception.
   ```js
  findUser().then(function (user) {
    return user.name;
  }, function (reason) {
    return 'default name';
  }).then(function (userName) {
    // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
    // will be `'default name'`
  });
   findUser().then(function (user) {
    throw new Error('Found user, but still unhappy');
  }, function (reason) {
    throw new Error('`findUser` rejected and we're unhappy');
  }).then(function (value) {
    // never reached
  }, function (reason) {
    // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
    // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
  });
  ```
  If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
   ```js
  findUser().then(function (user) {
    throw new PedagogicalException('Upstream error');
  }).then(function (value) {
    // never reached
  }).then(function (value) {
    // never reached
  }, function (reason) {
    // The `PedgagocialException` is propagated all the way down to here
  });
  ```
   Assimilation
  ------------
   Sometimes the value you want to propagate to a downstream promise can only be
  retrieved asynchronously. This can be achieved by returning a promise in the
  fulfillment or rejection handler. The downstream promise will then be pending
  until the returned promise is settled. This is called *assimilation*.
   ```js
  findUser().then(function (user) {
    return findCommentsByAuthor(user);
  }).then(function (comments) {
    // The user's comments are now available
  });
  ```
   If the assimliated promise rejects, then the downstream promise will also reject.
   ```js
  findUser().then(function (user) {
    return findCommentsByAuthor(user);
  }).then(function (comments) {
    // If `findCommentsByAuthor` fulfills, we'll have the value here
  }, function (reason) {
    // If `findCommentsByAuthor` rejects, we'll have the reason here
  });
  ```

  let result;
   try {
    result = findResult();

 * Find directions from A to B, or between any number of locations.
 * Consult the [Mapbox Directions API](https://www.mapbox.com/api-documentation/#directions)
 * for more documentation.
 *
 * @param {Array<Object>} waypoints an array of objects with `latitude`
 * and `longitude` properties that represent waypoints in order. Up to
 * 25 waypoints can be specified.
 * @param {Object} [options={}] additional options meant to tune
 * the request
 * @param {string} [options.profile=driving] the directions
 * profile, which determines how to prioritize different routes.
 * Options are `'driving-traffic'` for automotive routing which factors
 * in current and historic traffic conditions to avoid slowdowns,
 * `'driving'`, which assumes transportation via an
 * automobile and will use highways, `'walking'`, which avoids
 * streets without sidewalks, and `'cycling'`, which prefers streets
 * with bicycle lanes and lower speed limits for transportation via
 * bicycle.
 * @param {string} [options.account=mapbox] Account for the profile.
 * @param {string} [options.alternatives=true] whether to generate
 * alternative routes along with the preferred route.
 * @param {string} [options.geometries=geojson] format for the returned
 * route. Options are `'geojson'`, `'polyline'`, or `false`: `polyline`
 * yields more compact responses which can be decoded on the client side.
 * [GeoJSON](http://geojson.org/), the default, is compatible with libraries
 * like [Mapbox GL](https://www.mapbox.com/mapbox-gl/),
 * Leaflet and [Mapbox.js](https://www.mapbox.com/mapbox.js/). `false`
 * omits the geometry entirely and only returns instructions.
 * @param {string} [options.overview=simplified] type of returned overview
 * geometry. Can be `full` (the most detailed geometry available), `simplified`
 * (a simplified version of the full geometry), or `false`.
 * @param {Array<number|string>} [options.radiuses] an array of integers in meters
 * indicating the maximum distance each coordinate is allowed to move when
 * snapped to a nearby road segment. There must be as many radiuses as there
 * are coordinates in the request. Values can be any number greater than `0` or
 * they can be the string `unlimited`. If no routable road is found within the
 * radius, a `NoSegment` error is returned.
 * @param {boolean} [options.steps=false] whether to return steps and
 * turn-by-turn instructions. Can be `true` or `false`.
 * @param {boolean} [options.continue_straight] sets allowed direction of travel
 * when departing intermediate waypoints. If `true` the route will continue in
 * the same direction of travel. If `false` the route may continue in the
 * opposite direction of travel. Defaults to `true` for the `driving` profile
 * and `false` for the `walking` and `cycling` profiles.
 * @param {Array<Array>} [options.bearings] used to filter the road
 * segment the waypoint will be placed on by direction and dictates the angle
 * of approach. This option should always be used in conjunction with the
 * `radiuses` option. The parameter takes two values per waypoint: the first is
 * an angle clockwise from true north between `0` and `360`. The second is the
 * range of degrees the angle can deviate by. We recommend a value of `45` or
 * `90` for the range, as bearing measurements tend to be inaccurate. This is
 * useful for making sure we reroute vehicles on new routes that continue
 * traveling in their current direction. A request that does this would provide
 * bearing and radius values for the first waypoint and leave the remaining
 * values empty.If provided, the list of bearings must be the same length as
 * the list of waypoints, but you can skip a coordinate and show its position
 * by providing an empty array.

     * 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 and 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.
     *
     * In addition to lodash methods, wrappers have `Array` and `String` methods.
     *
     * The wrapper `Array` methods are:
     * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
     *
     * The wrapper `String` methods are:
     * `replace` and `split`

     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
     *
     * The chainable wrapper methods are:
