*
* MathJax/extensions/TeX/enclose.js
*
* Implements the \enclose macros, which give access from TeX to the

*
* Usage:
*
* \enclose{notation}{math} % enclose math using given notation
* \enclose{notation,notation,...}{math} % enclose with several notations
* \enclose{notation}[attributes]{math} % enclose with attributes
