Detailed Description

Index tables for the downward (distribute) message from a parent clique p to one child clique u.

The product space is that of clique p, combined with the separators to the siblings of u. The message multiplies p's potential, the down message p received from its own parent (if any) and the up messages of u's siblings, then sums onto the separator between p and u. Indexing follows CollectOp.
