## NAME
    [Heap::Elem::Str] - String Heap Elements

## SYNOPSIS
      use [Heap::Elem::Str]( StrElem );
      use [Heap::Fibonacci];

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

      foreach $i ( 'aa'..'bz' ) {
          $elem = StrElem( $i );
          $heap->add( $elem );
      }

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

## DESCRIPTION
    [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.
