For the inorder iterator do we need to use a list?

I assume that we have to use the given return for next() method.

//I set this to return null so that the project builds.  To do: delete return null, uncomment the following line, and make it work correctly

        return list.get(current++);

next() should return the next one item in the inorder traversal
