Automatic code documentation akin to doxygen.

[greole]

I was wondering whether github might consider to implement an automatic code documentation feature similar to what
doxygen does. This would beneficial for several reason:

• The automated documentation could be hosted and available directly at corresponding repository page. Thus users could users stay on github rather than repositories referring to external pages.
• Generated graphs, like the one shown below, could be used within wikis, issues, or discussions to illustrate code concepts.
• Having a great automatically generated documentation ultimately helps building better software.

I understand that implementing something like this is a major endeavour and probably this feature request has come up already a million times, so feel free to ignore.
