Create a new tiddler named MathJaxPlugin and tag it with
systemConfig. Copy the contents of the file tiddlywiki-mathjax.js
into it.
Any text in your tiddlers surrounded by $$..$$ (or \(..\)) will be
rendered as inline equation. Text surrounded by \[..\] will be
rendered as displayed equation.
The actual code as a small demo section you can see once you install the plugin.
