Create a range of integers starting at INTEGER1 and ending at
INTEGER2 (including both). Assume INTEGER1 <= INTEGER2.
IOTA* differs from IOTA in that it exludes INTEGER2 from the
generated range. Hence IOTA* can be used to create an empty
range, which IOTA cannot do.
(iota 17 21) ==> (17 18 19 20 21)
(iota 1 1) ==> (1)
(iota* 17 21) ==> (17 18 19 20)
(iota* 1 1) ==> ()
