Re: changing DdNode structure

No, it isn't straightforward. For performance reasons, CUDD assumes
that a DdNode is aligned to a 16-byte (32-byte) boundary on a 32-bit
(64-bit) machine. The alignment allows CUDD to make use of the low
order bits of addresses. This is turn is used to make a computed
table entry also fit within 16 bytes (on a 32-bit machine).
