[Feature request] Adding MathJax or KaTeX support

[scaomath]

I wonder how difficult it is to add MathJax/KaTeX support for the plugin so that certain predefined delimiters will trigger the rendering of LaTeX, so that the users can use switches in _config.yml.

Thanks a lot.

Bump? -- Now that github markdown supports latex, it seems like it should be possible to make it work with utterances too, right? I have mathjax running on my blog already, and I'm sure that's likely to be true for many of the people interested in this feature.

+1 to this! This would make Utterances a go-to solution for adding comments to math blogs!

Some Markdown+MathJax comment:

$$\sum_{k=0}^\infty q^k = \frac{1}{1-q}$$
