- * Provides getElementsByClassName method, if there is no native

- *
- * NOTE that there are limits and differences compared to native
- * getElementsByClassName as defined by e.g.:
- * https://developer.mozilla.org/en/DOM/document.getElementsByClassName
- * http://www.whatwg.org/specs/web-apps/current-work/multipage/dom.html#dom-getelementsbyclassname
- * http://www.whatwg.org/specs/web-apps/current-work/multipage/dom.html#dom-document-getelementsbyclassname
- *
- * Namely, this implementation supports only single class name as
- * argument and not set of space-separated tokens representing classes,
- * it returns Array of nodes rather than live NodeList, and has
- * additional optional argument where you can limit search to given tags
- * (via getElementsByTagName).
- *
- * Based on
