 16:    Input Parameters:
 17: +  comm - the MPI communicator to use 
 18: .  n - local vector length (or PETSC_DECIDE to have calculated if N is given)
 19: -  N - global vector length (or PETSC_DETERMINE to have calculated if n is given)

 22: .  vv - the vector

 24:    Notes:
 25:    Use VecDuplicate() or VecDuplicateVecs() to form additional vectors of the
