Add @template annotation to facilitate route definition

[mysticfall]

Previously, there was PageController which can be used in conjunction with RouteProvider to easily declare template URL to be used for each controller instance.

However, as we replaced that trait with the recent constructor based DI implementation, we need another method to provide the functionality now.

We could use something like @template("/templates/edit.html") and probably, @title("Page Title") as well to facilitate defining routes.

I think you could use an object companion for this. (I use this in my project)

class RoutingConfig(routeProvider: RouteProvider) extends Config {
  override def initialize() {
    super.initialize()
    routeProvider
        .when("/", MySampleController.route)
  }
}

object MySampleController {
    val route = Route("partials/controller/myTemplateUrl.htm", "Title", "mySampleController")
}

@injectable("mySampleController")
class MySampleController(scope: MyScope, http: HttpService) extends AbstractController[MyScope](scope) {
    ... your code ...
}

But I'm agree, an annotation solution will be more consise.
