"""
In order to get at more extensions, I wanted to use
   https://pythonhosted.org/Markdown instead of
   https://github.com/trentm/python-markdown2

So I made this custom parser ala plim docs here:
   http://plim.readthedocs.org/en/latest/en/extensions.html

Extensions available are here:
   https://pythonhosted.org/Markdown/extensions/index.html
