! ---------------------------------------------------------------------
! --- Routine 'ranint' generates an random array of 'n' integers with 
!     values in the range [low, hi]. When [low, hi] = [1,n], 
!     'ranint_array' is not neccesarily a permutation, i.e., 
!      ranint_array(i) might be equal to ranint_array(j) for some i, j.
