(function () {
  if(!window.console) {
    console = {
      log: function() {
        var str = "";
        for(var i = 0; i < arguments.length; i++) {
          str += arguments[i];
        }
        document.body.appendChild(document.createTextNode(str));
        document.body.appendChild(document.createElement('br'));
