comparing LABjs and $script.js when parallel loading with execution order dependencies

bench-LABjs-parallel.html

    <script src="../vendor/lab2.min.js"></script>
    <script type="text/javascript">
      var start = (+new Date);

      // load some scripts dependent on each other (in parallel but preserving execution order)
      $LAB
      .setOptions({AlwaysPreserveOrder:true})
      .script('a.js')
      .script('b-needs-a.js')
      .script('c-needs-b.js')
      .wait(function(){
        a() + b() + c();

        // benchmark time!
        document.getElementById('total').innerHTML = (+new Date) - start;
        
      });
    </script>

bench-scriptjs-(not)parallel.html

    <script src="../dist/script.js"></script>
    <script type="text/javascript">
      var start = (+new Date);

      // load some scripts dependent on each other (as nested $script calls, so NOT parallel)
      $script('a.js',function(){
        $script('b.js',function(){
          $script('c.js',function(){
            a() + b() + c();

            // benchmark time!
            document.getElementById('total').innerHTML = (+new Date) - start;
          });
        });
      });
    </script>
