-
-  promise.then(function(value){

-  `RSVP.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 = RSVP.resolve(1);
-  let promise2 = RSVP.resolve(2);
-  let promise3 = RSVP.resolve(3);
-  let promises = [ promise1, promise2, promise3 ];
-
-  RSVP.Promise.all(promises).then(function(array){
-    // The array here would be [ 1, 2, 3 ];
-  });
-  ```
-
-  If any of the `promises` given to `RSVP.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 = RSVP.resolve(1);
-  let promise2 = RSVP.reject(new Error("2"));
-  let promise3 = RSVP.reject(new Error("3"));
-  let promises = [ promise1, promise2, promise3 ];
-
-  RSVP.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.

-/**
-  `RSVP.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 RSVP.Promise(function(resolve, reject){
-    setTimeout(function(){
-      resolve('promise 1');
-    }, 200);
-  });
-
-  let promise2 = new RSVP.Promise(function(resolve, reject){
-    setTimeout(function(){
-      resolve('promise 2');
-    }, 100);
-  });
-
-  RSVP.Promise.race([promise1, promise2]).then(function(result){
-    // result === 'promise 2' because it was resolved before promise1
-    // was resolved.
-  });
-  ```
-
-  `RSVP.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 RSVP.Promise(function(resolve, reject){
-    setTimeout(function(){
-      resolve('promise 1');
-    }, 200);
-  });
-
-  let promise2 = new RSVP.Promise(function(resolve, reject){
-    setTimeout(function(){
-      reject(new Error('promise 2'));
-    }, 100);
-  });
-
-  RSVP.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
-  });
-  ```
-

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

-/**
-  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
-  @param {String} label optional string for labeling the promise.

-  /**

-    }, 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
-    });
-    ```
-

-/**
-  `RSVP.denodeify` takes a 'node-style' function and returns a function that
-  will return an `RSVP.Promise`. You can use `denodeify` in Node.js or the
-  browser when you'd prefer to use promises over using callbacks. For example,
-  `denodeify` transforms the following:
-
-  ```javascript
-  let fs = require('fs');
-
-  fs.readFile('myfile.txt', function(err, data){
-    if (err) return handleError(err);
-    handleData(data);
-  });
-  ```
-
-  into:
-
-  ```javascript
-  let fs = require('fs');
-  let readFile = RSVP.denodeify(fs.readFile);
-
-  readFile('myfile.txt').then(handleData, handleError);
-  ```
-
-  If the node function has multiple success parameters, then `denodeify`
-  just returns the first one:
-
-  ```javascript
-  let request = RSVP.denodeify(require('request'));
-
-  request('http://example.com').then(function(res) {
-    // ...
-  });
-  ```
-
-  However, if you need all success parameters, setting `denodeify`'s
-  second parameter to `true` causes it to return all success parameters
-  as an array:
-
-  ```javascript
-  let request = RSVP.denodeify(require('request'), true);
-
-  request('http://example.com').then(function(result) {
-    // result[0] -> res
-    // result[1] -> body
-  });
-  ```
-
-  Or if you pass it an array with names it returns the parameters as a hash:
-
-  ```javascript
-  let request = RSVP.denodeify(require('request'), ['res', 'body']);
-
-  request('http://example.com').then(function(result) {
-    // result.res
-    // result.body
-  });
-  ```
-
-  Sometimes you need to retain the `this`:
-
-  ```javascript
-  let app = require('express')();
-  let render = RSVP.denodeify(app.render.bind(app));
-  ```
-
-  The denodified function inherits from the original function. It works in all
-  environments, except IE 10 and below. Consequently all properties of the original
-  function are available to you. However, any properties you change on the
-  denodeified function won't be changed on the original function. Example:
-
-  ```javascript
-  let request = RSVP.denodeify(require('request')),
-      cookieJar = request.jar(); // <- Inheritance is used here
-
-  request('http://example.com', {jar: cookieJar}).then(function(res) {
-    // cookieJar.cookies holds now the cookies returned by example.com
-  });
-  ```
-
-  Using `denodeify` makes it easier to compose asynchronous operations instead
-  of using callbacks. For example, instead of:
-
-  ```javascript
-  let fs = require('fs');

-  Promises A+ specifies that any exceptions that occur with a promise must be

-  this reason, it is recommended that you always specify a second rejection
-  handler function to `then`. However, `RSVP.rethrow` will throw the exception
-  outside of the promise, so it bubbles up to your console if in the browser,
-  or domain/cause uncaught exception in Node. `rethrow` will also throw the
-  error again so the error can be handled by the promise per the spec.

-  ```javascript
-  function throws(){
