 *  MathJax/extensions/TeX/noErrors.js
 *  
 *  Prevents the TeX error messages from being displayed and shows the
 *  original TeX code instead.  You can configure whether the dollar signs
 *  are shown or not for in-line math, and whether to put all the TeX on
 *  one line or use multiple-lines.
 *  
 *  To configure this extension, use
 *  
 *      MathJax.Hub.Config({
 *        TeX: {
 *          noErrors: {
 *            inlineDelimiters: ["",""],   // or ["$","$"] or ["\\(","\\)"]
 *            multiLine: true,             // false for TeX on all one line
 *            style: {
 *              "font-size":   "90%",
 *              "text-align":  "left",
 *              "color":       "black",
 *              "padding":     "1px 3px",
 *              "border":      "1px solid"
 *                // add any additional CSS styles that you want
 *                //  (be sure there is no extra comma at the end of the last item)
 *            }
 *          }
 *        }
 *      });
 *  
 *  Display-style math is always shown in multi-line format, and without
 *  delimiters, as it will already be set off in its own centered
 *  paragraph, like standard display mathematics.
 *  
 *  The default settings place the invalid TeX in a multi-line box with a
 *  black border.  If you want it to look as though the TeX is just part of
 *  the paragraph, use
 *
 *      MathJax.Hub.Config({
 *        TeX: {
 *          noErrors: {
 *            inlineDelimiters: ["$","$"],   // or ["",""] or ["\\(","\\)"]
 *            multiLine: false,
 *            style: {
 *              "font-size": "normal",
 *              "border": ""
 *            }
 *          }
 *        }
 *      });
 *  
 *  You may also wish to set the font family, as the default is "serif"
