the class Server method start.

    // In order to use a template we first need to create an engine
    final FreeMarkerTemplateEngine engine = FreeMarkerTemplateEngine.create(vertx);
    // Entry point to the application, this will render a custom template.

        // we define a hardcoded title for our application
        JsonObject data = new JsonObject().put("name", "Vert.x Web").put("path", ctx.request().path());
