* MathJax/config/MMLorHTML.js
*
* Chooses between the NativeMML and HTML-CSS output jax depending
* on the capabilities of the browser and configuration settings
* of the page.
*
* This file should be added to the config array when configuring
* MathJax. Note that if you include this, you should NOT include
* an output jax in the jax array (it will be added for you by
* this file).
*
* You can specify the preferred output jax on a global or
* browser-by-browser basis. To specify it globally, use
*
* MathJax.Hub.Config({
* MMLorHTML: {prefer: "MML"} // or "HTML"
* });
*
* To specify on a browser-by-borwser basis, use
*
* MathJax.Hub.Config({
* MMLorHTML: {prefer: {
* MSIE: "MML",
* Firefox: "MML",
* Opera: "HTML",
* other: "HTML"
* }}
* });
