RST compiler (not needed only .md files are supported)

[ClimenteA]

First attempt for sphinx support was to use an RST to HTML compiler. I choosed pandoc looks like this is a standard package for file conversions. Other npm packages with rst to html conversion were covering only the most basic declarations.

pandoc npm package didn't worked well. Currently, pandoc needs to be installed so rst to html to work, but we can create a wrapper around pandoc binary if RST support is needed at some point (markdown rules 😄 ).

RST compiler doesn't work on sphinx docs because of various sphinx addons which have their own placeholder declarations (see automodapi).

XML is the closest format which we can take, parse and generate our own html files.
