------------------------------------------------------------------

Null nodes are nodes with null probability and are not merged by AIB. It is convenient, however, to treat them as follows:

• we pretend that AIB merged those nodes at the very beginning into a single cluster (as they, after all, yield zero information drop).

• we attach this cluster to the root as the very last step (as we do not want to change other nodes.
