And what if "2" has a couple of children? And one of those children has 
children of it's own?
You see, I will be needing multiple levels and will need to know if a 
node is already there at some level, and be able to add a child to that 
node on the fly, and to be able to traverse the tree in different ways, 
so I would eventually develop a tree library which is what I'm looking for.
