public boolean evaluate(SemanticGraph sg,

Remove all edges from gov to dep that match the relation name.
Either gov or dep can be **WILDNODE**, representing that all edges to or from the other node of that type should be removed.
You cannot set both gov and dep to **WILDNODE**, though.
This will not update anything the second time executed on the same graph.
