Notes: The index sets isapp and ispetsc must contain the all the integers 0 to napp-1 (where napp is the length of the index sets) with no duplicates;
that is there cannot be any "holes".
Comparing with <A HREF="../AO/AOCreateBasicIS.html#AOCreateBasicIS">AOCreateBasicIS</A>(), this routine trades memory with message communication.
