  /**
  `Y.App` extension that provides pjax-style content fetching and handling.
  
  This makes it easy to fetch server rendered content for URLs using Ajax. The
  HTML content returned from the server will be view-ified and set as the app's
  main content, making it seamless to use a mixture of server and client rendered
  views.
  
  When the `"app-content"` module is used, it will automatically mix itself into
  `Y.App`, and it provides three main features:
  
    - **`Y.App.Content.route`**: A stack of middleware which forms a pjax-style
      content route.
  
    - **`loadContent()`**: Route middleware which load content from a server. This
      makes an Ajax request for the requested URL, parses the returned content and
      puts it on the route's response object.
  
    - **`showContent()`**: Method which provides an easy way to view-ify HTML
      content which should be shown as an app's active/visible view.
  
  The following is an example of how these features can be used:
  
      // Creates a new app and registers the `"post"` view.
      var app = new Y.App({
          views: {
              post: {type: Y.PostView}
          }
      });
  
      // Uses a simple server rendered content route for the About page.
      app.route('/about/', Y.App.Content.route);
  
      // Uses the `loadContent()` middleware to fetch the contents of the post
      // from the server and shows that content in a `"post"` view.
      app.route('/posts/:id/', 'loadContent', function (req, res, next) {
          this.showContent(res.content.node, {view: 'post'});
      });

      Sets this app's `activeView` attribute using the specified `content`.
  
      This provides an easy way to view-ify HTML content which should be shown as
      this app's active/visible view. This method will determine the appropriate
      view `container` node based on the specified `content`. By default, a new
      `Y.View` instance will be created unless `options.view` is specified.
  
      Under the hood, this method calls the `showView()` method, so refer to its
      docs for more information.
  
      @method showContent
      @param {HTMLElement|Node|String} content The content to show, it may be
          provided as a selector string, a DOM element, or a `Y.Node` instance.
      @param {Object} [options] Optional objects containing any of the following
          properties in addition to any `showView()` options:
  
        @param {Object|String} [options.view] The name of a view defined in this
            app's `views`, or an object with the following properties:
  
          @param {String} options.view.name The name of a view defined in this
              app's `views`.
          @param {Object} [options.view.config] Optional configuration to use when
              creating the new view instance. This config object can also be used
              to update an existing or preserved view's attributes when
              `options.update` is `true`. **Note:** If a `container` is specified,
              it will be overridden by the `content` specified in the first
              argument.
  
      @param {Function} [callback] Optional callback function to call after the
          new `activeView` is ready to use. **Note:** this will override
          `options.callback` and it can be specified as either the second or third
          argument. The function will be passed the following:
  
        @param {View} callback.view A reference to the new `activeView`.
