/*
 *  jsMath-easy-load.js
 *  
 *  Part of the jsMath package for mathematics on the web.
 *
 *  This file is used to load jsMath with one easy <SCRIPT>
 *  command in your HTML file.  It is called by the files
 *  in the jsMath/easy/ directory.  It expects that the jsMath.Easy
 *  array has been initialized before it is called.
