Export to markdown

[macteo]

I'm facing the needs of exporting the documentation created with Apipie to be used on pdf documents and other sites and I found that there isn't an export feature.

I used the rake apipie:static to get the html and found that I cannot convert it to markdown with Pandoc.

It would be very useful if you add an export method to create static markdown pages.

A possible template could be this one.

I needed that feature so I've created the exporter as rake task rake apipie:markdown.
It isn't polished nor tested and includes some dependancies and layout changes related to my project but you can find it if you need it on this repo.

Side note: I've also added a success section for each method (copy of the errors) to represent successful (200) request and the json returned. The examples are (for me at least) more useful to post curl o ajax functions.

Thanks for heads up, let's keep this issue open so that we don't forget about that.
