For DD functions that return a DdNode*, errors can be reported by returning NULL.
Functions that have no return value (printing, etc) or a data value (double, etc)
should set the flag, which can be converted into an CuddOutOfMemoryException on
the PRISM side using JDD.checkForCuddError()

The native DD/CuDD methods return NULL to indicate that
an out-of-memory error in CuDD has occurred. Before, we
constructed a JDDNode for this NULL ptr, which would lead
to a SIGSEGV crash the next time any operation
(ref, deref, etc) would be performed on that JDDNode.
