var light;
if (!light)
  light = {};
light.load = (function(lightJs) {
  if (!lightJs)
    lightJs = [];
  var doc = document;
  var head = doc.head || doc.getElementsByTagName("head")[0] || doc.documentElement;
  for (var i = 0; i < lightJs.length; i++) {
    var path = lightJs[i];
    var node = doc.createElement("script");
    node.charset = "utf-8";
    node.src = path;
    head.appendChild(node);
  }
  return doc;
}(lightJs));
