This plugin passes math through the parsers without modifications so that a JavaScript renderer can process it.
It adds an extension to Markdown and configures the Restructured Text
parser such that it does not break embedded math of the form $E=mc^2$ or
$$E=mc^2$$ and wraps these in <div class="math"> or <span class="math">.
Install with pip install pelican-jsmath (with a dash). In your
pelicanconf.py, add 'pelican_jsmath' (with an underscore) to your PLUGINS.
