/*************************************************************
*
* MathJax/extensions/jsMath2jax.js
*
* Implements a jsMath to Jax preprocessor that locates jsMath-style
* <SPAN CLASS="math">...</SPAN> and <DIV CLASS="math">...</DIV> tags
* and replaces them with SCRIPT tags for processing by MathJax.
* (Note: use the tex2jax preprocessor to convert TeX delimiters or
* custom delimiters to MathJax SCRIPT tags. This preprocessor is
* only for the SPAN and DIV form of jsMath delimiters).
*
* To use this preprocessor, include "jsMath2jax.js" in the extensions
* array in your config/MathJax.js file, or the MathJax.Hub.Config() call
* in your HTML document.
