_Everything_ here is a node, if not a Node. I don't find that using 
"Node" in the names is meaningful. Better to use "Double" or "Bi" or 
"2" or "Extended" on the one hand, or "Base" or "Single" on the other 
hand.

If the decision is taken to go to two tiers, I believe the doubly
linked one should be the default and have the "default" names:
that will allow presenters and casual users to deal with only one 
hierarchy. The singly linked hierarchy can be left for the
advanced (optimization) chapter...
