Slowing migrating this to how it was intended.

Services are kind of useless if they can't filter/query.

GormService was originally modeled afterRestfulController<T>, but that wasn't really necessary.

This is another step that migrates towards making the scaffold service more useful

My final version of GormService allows querying by params and counting by params. Currently I am using this as a base class that I extend with a more meaningful implementation.

Allows this

@Scaffold(domain = User)
class UserService {
    List<User> list(Map args) {
        args.firstName? User.findAllByFirstName(args.firstName, args) : User.list(args)
    }

    Long count(Map args) {
        args.firstName? User.countByFirstName(args.firstName) : User.count()
    }
} 

@Scaffold(RestfulServiceController<User>)
class UserController {}

now works and is properly paginated:
