I've stripped the names to protect the compiler, but really there should be some checks involved so that entries like this aren't in trees. I mean, aren't computers supposed to be capable of catching this type of mistakes? I thought that was something programming could do--catch data entry errors where children are born before their parents.
Users should get an error message or when this type of information is entered.
In fact, I'd rather see improvements in that regard instead of more leaf improvements.
