/// Used for retrieving and rendering the file you input through the macro `handlebars_resources_initialize!` as a `HandlebarsResponse` instance with rendered HTML. When its `respond_to` method is called, three HTTP headers, **Content-Type**, **Content-Length** and **Etag**, will be automatically added, and the rendered HTML can optionally not be minified.
