       Heap::Elem::Str is used to wrap string values into an element that can be managed on a heap.  The top of
       the heap will have the smallest element still remaining.  (See Heap::Elem::StrRev if you want the heap to
       always return the largest element.)

       The details of the Elem interface are described in Heap::Elem.

       The details of using a Heap interface are described in Heap.
