NAME
       Heap::Elem::Num - Numeric Heap Elements

SYNOPSIS
         use Heap::Elem::Num( NumElem );
         use Heap::Fibonacci;

         my $heap = Heap::Fibonacci->new;
         my $elem;

         foreach $i ( 1..100 ) {
             $elem = NumElem( $i );
             $heap->add( $elem );
         }

         while( defined( $elem = $heap->extract_top ) ) {
             print "Smallest is ", $elem->val, "\n";
         }

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.

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