public static interface TreeDef.Parented<T>
A "doubly-linked" tree, where nodes know about both their parent and their children.
It is CRITICAL that the TreeDef.Parented is consistent - if Vader claims that Luke
and Leia are his children, then both Luke and Leia must say that Vader is their parent.
If Luke or Leia don't agree that Vader is their father, then the algorithms that use
this TreeDef.Parented are likely to fail in unexpected ways.
