Add documentation engine

[tyzoid]

Since RestServer already performs reflection into the class maps to generate an API, we can tap into this existing map to build up an interface for navigating and documenting the API automatically.

An initial attempt can be found in feature/documentation

hi @tyzoid thanks for the this feature. Do you have any documentation to get the documentation to work? Calling it on / does prints a 404 for me.

When I check the /map I do see the new documentation get parsed (name, description,param)
