.IX Header "DESCRIPTION"
Heap::Elem::Num is used to wrap numeric 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::NumRev
if you want the heap to always return the largest element.)

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