/**
  `Promise.reject` returns a promise rejected with the passed `reason`.
  It is shorthand for the following:

  ```javascript
  var promise = new Promise(function(resolve, reject){
    reject(new Error('WHOOPS'));
  });

  promise.then(function(value){
    // Code here doesn't run because the promise is rejected!
  }, function(reason){
    // reason.message === 'WHOOPS'
  });
  ```

  Instead of writing the above, your code now simply becomes the following:

  ```javascript
  var promise = Promise.reject(new Error('WHOOPS'));

  promise.then(function(value){
    // Code here doesn't run because the promise is rejected!
  }, function(reason){
    // reason.message === 'WHOOPS'
  });
  ```

  @method reject
  @static
  @param {Any} reason value that the returned promise will be rejected with.
  @param {String} label optional string for identifying the returned promise.
  Useful for tooling.
  @return {Promise} a promise rejected with the given `reason`.
