In order to return an iterator to a new node we need to return a concrete type of iterator. If we want to make it work for any kind of iterator we need to implement converting constructors. This is not the best option and not the fastest one, but it works. Most of the times we'll be using pre-order iterators, so that's why we need to return a pre-order iterator.
