Yes, I totally agree with you. But I think we should move "composition" package to "algorithm" because of classes of "composition" are meta-algothms. Class ModelComposition with "aggregator"-package can be moved to "model". Also, we should refactor Dataset-classes. There are two different Dataset.java files at least.
