Markdown: __map_ parameters

[christophfroehlich]

I kindly submit a feature request for the markdown generation 😇

• __map_ : these ones are completely ignored now

My understanding of the python/jinja scripts is too low. But if someone points me in the direction I could help to implement these.

@christophfroehlich thank you for the issue. I don't clearly understand your first point. Would you mind breaking it into a separate issue and leaving this about the non-support for map. I don't have time to work on this now but will happily accept PRs that fix this. I'll try to find some time to better document the python/jinja so it is easier to modify for you. I too struggle to edit it efficiently and some better design documentation would be good for me to write because it would force me to finally learn the little details.

@tylerjw see #126 for a more detailed explanation of my problem with the nested structures.
Regarding the map parameters here: Somethink like we have with the JTC docs would be good enough:
