 *  MathJax/extensions/TeX/noUndefined.js
 *  
 *  This causes undefined control sequences to be shown as their macro
 *  names rather than producing an error message.  So $X_{\xxx}$ would
 *  display as an X with a subscript consiting of the text "\xxx".
 *  
 *  To configure this extension, use for example
 *  
 *      MathJax.Hub.Config({
 *        TeX: {
 *          noUndefined: {
 *            attributes: {
 *              mathcolor: "red",
 *              mathbackground: "#FFEEEE",
 *              mathsize: "90%"
 *            }
 *          }
 *        }
 *      });
