    Produce a list containing the progressive halving of an integral.

    scala> halves(15)
List(15, 7, 3, 1)

scala> halves(100)

  14. def list[A](xs: List[A]): List[List[A]]

    Shrink a list by edging towards the empty list.

    Shrink a list by edging towards the empty list.

    scala> list(List(1, 2, 3))
List(List(), List(2, 3), List(1, 3), List(1, 2))

>>> list("abcd".toList)
List("", "cd", "ab", "bcd", "acd", "abd", "abc")

    Note we always try the empty list first, as that is the optimal shrink.
