int isbddvarinsupport( BddSystem, BddNode, Variable )
bddsystem *BddSystem;

isbddvarinsupport tests if the variable number Variable appears in the support of the bdd node BddNode, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.
isbddvarinsupport returns 1 if Variable appears, 0 otherwise.
variable xxx out of range, error !"
The Variable parameter must be less or equal to the BddSystem->NUM_BER_VAR
field.
