  (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
  m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
  })(window,document,'script','//www.google-analytics.com/analytics.js','ga');

  window.ga('create', 'UA-XXXXXXXX-X')

  return {
    send: function () {
      var args = Array.prototype.slice.call(arguments, 0)
      args.unshift('send')
      window.ga.apply(window, args)
    }
