Error in TreeADDs

[Francisco Javier Díez]

When a variable X makes part of a TreeADDPotential and one of the states is renamed, the branches of the tree related to that state become inconsistent. The error can be detected by saving and reopening the network. It seems that the cause of the problem is that the branches of the tree are pointing to the name of the state (a string), instead of pointing at the state itself.
