`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'});

@param {String} options.view.name The name of a view defined in this

it will be overridden by the `content` specified in the first
