* A TemplateViewRoute is built up by a path (for url-matching) and the implementation of the 'render' method.
* TemplateViewRoute instead of returning the result of calling toString() as body, it returns the result of calling render method.
*
* The primary purpose of this kind of Route is provide a way to create generic and reusable components for rendering output using a Template Engine. For example to render objects to html by using Freemarker template engine..
