  9:    VecCreateMPI - Creates a parallel vector.
 11:    Collective
 13:    Input Parameters:
 14: +  comm - the MPI communicator to use
 15: .  n - local vector length (or PETSC_DECIDE to have calculated if N is given)
 16: -  N - global vector length (or PETSC_DETERMINE to have calculated if n is given)
 18:    Output Parameter:
 19: .  vv - the vector
 21:    Notes:
 22:    Use VecDuplicate() or VecDuplicateVecs() to form additional vectors of the
 23:    same type as an existing vector.
