-/**
-  `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

-  `Promise.race` is deterministic in that only the state of the first

-/**
-  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;
-  });
-  ```

-  @param {Function} 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
-  });
-  ```
-   Simple Example
-  --------------
-   Synchronous Example
-   ```javascript
-  let result;
-   try {
-    result = findResult();
-    // success
-  } catch(reason) {
-    // failure
-  }
-  ```
-   Errback Example
-   ```js
-  findResult(function(result, err){
-    if (err) {
-      // failure
-    } else {
-      // success
-    }

-   Synchronous Example

-  }
-  ```
-   Errback Example
-   ```js
