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.
