Support for Math Typesetting

Hi,

Does the template currently support Math Typesetting?

Thanks,
Alexis

I added MathJaX support using Shortcode.

In layouts/shortcodes/MathJaX.html:

{{ .Inner }}

In forty/layouts/partials/header.html:

...
{{ with .Site.Params.favicon }}
	<link rel="shortcut icon" type="image/x-icon" href="{{ . | absURL }}">
	<link rel="icon" type="image/x-icon" href="{{ . | absURL }}">
{{ end }}
	
{{ if .Page.Params.enableMathJaX }}
	{{ partial "MathJaX.html" . }}
{{ end }}
...

In layouts/partials/MathJax.html:

<script type="text/x-mathjax-config">
  MathJax.Hub.Config({
    extensions: ["tex2jax.js"],
    jax: ["input/TeX", "output/HTML-CSS"],
    tex2jax: {
      inlineMath: [ ['$','$'], ["\\(","\\)"] ],
      displayMath: [ ['$$','$$'], ["\\[","\\]"] ],
      processEscapes: true
    },
    "HTML-CSS": { fonts: ["TeX"] }
  });
</script>
<script type="text/javascript"
   src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.7/MathJax.js?config=TeX-AMS_CHTML">
</script>

In the markdown file:

{{< MathJaX >}}
$$
\begin{vmatrix}a & b\\
c & d
\end{vmatrix}
$$
{{< /MathJaX >}}
