Revise the relations when the domain of a variable changes

[Francisco Javier Díez]

The relation between a node and its parents depends on the domains of all the variables in the family. This is checked when changing the relation type. It should also be checked when changing the domain of a variable; otherwise, the network might end up being in an inconsistent state.

I have to check this again.
