Computes the intesection of two sets of literals represented as BDDs.

Each set is represented as a cube of the literals in the set. The empty set is represented by the constant 1. No variable can be simultaneously present in both phases in a set.

**Returns:**- a pointer to the BDD representing the intersected sets, if successful; NULL otherwise.

**Side effects**- None

Performs the recursive step of Cudd_bddLiteralSetIntersection.

Scans the cubes for common variables, and checks whether they agree in phase.

**Returns:**- a pointer to the resulting cube if successful; NULL otherwise.

**Side effects**- None
