/**
 *
 * Loader to add ol.css, ol.js and the example-specific js file to the
 * documents.
 *
 * This loader is used for the hosted examples. It is used in place of the
 * development loader (examples/loader.js).
 *
 * ol.css and ol.js are built with Plovr/Closure, based build/ol.json.
 * (`make build` should build them). They are located in the ../build/
 * directory, relatively to this script.
 *
 * The script should be named loader.js. So it needs to be renamed to
 * loader.js from loader_hosted_examples.js.
 *
 * Usage:
 *
 *     <script src="../loader.js?id=my-demo"></script>
