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, "
";
	 }

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.
