genom3

I think we already discussed it a bit, but I think the situation has changed a bit since codels now have a genom_context in them.

The idea would be to have some kind of "standardized" genom interface for logging, which can be implemented in each template, reusing tools provided by the different middleware. It would allow to reuse tools for each middleware, and provides some unified way to log information in genom3 module (instead of the current mess in genom2 modules).
