-
- alpha (1) -+-> beta (69)
- \-> beta (69).
-
- This describes a tree with three nodes. Two of them are links
- (beta). In that case, both the "beta" node have an id of "1:69".
- So if one calls openNode on any of them, what happens is that only
- one actually gets opened. To prevent that, I change the id of the
- node on the fly to make sure there are only unique id's.
