ISCreateGeneral
Creates a data structure for an index set containing a list of integers. 
Synopsis
#include "petscis.h"  
PetscErrorCode  ISCreateGeneral(MPI_Comm comm,PetscInt n,const PetscInt idx[],PetscCopyMode mode,IS *is)
Collective on MPI_Comm
Input Parameters
|  | comm | - the MPI communicator | 
|  | n | - the length of the index set | 
|  | idx | - the list of integers | 
|  | mode | - see PetscCopyMode for meaning of this flag. | 
Output Parameter
is  -the new index set
Notes
When the communicator is not MPI_COMM_SELF, the operations on IS are NOT
conceptually the same as MPI_Group operations. The IS are then
distributed sets of indices and thus certain operations on them are
collective.
