It seems like relationLoaded() must be provided by classes using this trait. How about adding it as abstract method to this trait?

It seems like getRelation() must be provided by classes using this trait. How about adding it as abstract method to this trait?

It seems like morphMany() must be provided by classes using this trait. How about adding it as abstract method to this trait?
