///////////////////////////////////////////////////////////////
// StripLoad is an extension for Loader.js
// Call the StripLoad.stripLoad(); method passing it a selector
// StripLoad will then remove all images within the selector
// preload them using Loader.js
// Once completing loading it will append the images back
// into the html where they came from
// Alternatively you can call the methods individually eg
// StripLoad.stripLoad.strip("#myDiv").load();
// then bind an event listener and listen for the LOADED event
// you can then call the append method StripLoad.append();
