    parentNode = null

 2. currentNode = new Node('root')
    rootNode = currentNode
    parentNode = null
 
 3. currentNode = new Node('child1')
    parentNode = root
 
 4. currentNode = new Node('child2')
    parentNode = child1
 
 5. close child2
    currentNode = child1
    parentNode = root

 6. close child1
    currentNode = root
    parentNode = null

 7. currentNode = new Node('child3')
    parentNode = root

 8. close child3
    currentNode = root
    parentNode = null

 9. close root
    currentNode = null
    parentNode = null



    Sooooo

 1. parentNode = currentNode.parentNode (parentNode is local!!)
