	      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
	      Useful for tooling.
	      @constructor
	    */
	    function lib$es6$promise$promise$$Promise(resolver) {
	      this[lib$es6$promise$$internal$$PROMISE_ID] = lib$es6$promise$$internal$$nextId();
	      this._result = this._state = undefined;
	      this._subscribers = [];

	      if (lib$es6$promise$$internal$$noop !== resolver) {
	        typeof resolver !== 'function' && lib$es6$promise$promise$$needsResolver();
	        this instanceof lib$es6$promise$promise$$Promise ? lib$es6$promise$$internal$$initializePromise(this, resolver) : lib$es6$promise$promise$$needsNew();
	      }
	    }

	    lib$es6$promise$promise$$Promise.all = lib$es6$promise$promise$all$$default;
	    lib$es6$promise$promise$$Promise.race = lib$es6$promise$promise$race$$default;
	    lib$es6$promise$promise$$Promise.resolve = lib$es6$promise$promise$resolve$$default;
	    lib$es6$promise$promise$$Promise.reject = lib$es6$promise$promise$reject$$default;
	    lib$es6$promise$promise$$Promise._setScheduler = lib$es6$promise$asap$$setScheduler;
	    lib$es6$promise$promise$$Promise._setAsap = lib$es6$promise$asap$$setAsap;
	    lib$es6$promise$promise$$Promise._asap = lib$es6$promise$asap$$asap;

	    lib$es6$promise$promise$$Promise.prototype = {
	      constructor: lib$es6$promise$promise$$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
	      });
	      ```

	      Simple Example
	      --------------

	      Synchronous Example

	      ```javascript
	      var result;

	      try {

	     * 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.
	     *
