The promise will be resolved with no parameters as information should travel through the dispatcher and stores. To reject the promise, return a falsy value from the action's method. The dispatcher will not be called if the returned value is falsy or has no actionType.

+      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
+      var 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){
+          var 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
+      @param {String} label optional string for labeling the promise.
+      Useful for tooling.
+      @constructor
+    */
+    function $$es6$promise$promise$$Promise(resolver, label) {
+      this._id = $$es6$promise$promise$$counter++;
+      this._label = label;
+      this._state = undefined;
+      this._result = undefined;
+      this._subscribers = [];
+
+      if ($$$internal$$noop !== resolver) {
+        if (!$$utils$$isFunction(resolver)) {
+          $$es6$promise$promise$$needsResolver();
+        }
+
+        if (!(this instanceof $$es6$promise$promise$$Promise)) {
+          $$es6$promise$promise$$needsNew();
+        }
+
+        $$$internal$$initializePromise(this, resolver);
+      }
+    }

+    $$es6$promise$promise$$Promise.all = $$promise$all$$default;
+    $$es6$promise$promise$$Promise.race = $$promise$race$$default;
+    $$es6$promise$promise$$Promise.resolve = $$promise$resolve$$default;
+    $$es6$promise$promise$$Promise.reject = $$promise$reject$$default;
+
+    $$es6$promise$promise$$Promise.prototype = {
+      constructor: $$es6$promise$promise$$Promise,
+
+    /**
+      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
+      });
+      ```
+

+
+      Synchronous Example
+
+      ```javascript
+      var result;
+
+      try {
