Code inspection

[valberg]

It would be awesome to have a way to do inspection of python code. The use case is that when browsing code, it is often a big benefit to be able to go to the declaration of a function/variable/class, and also be able to see where this function/variable/class is in use. Thus:

• Somehow setup some workers to do inspection on code (use inspect module)
• Store this metadata in redis (unless the inspection performance is sub par, then maybe something more persistent is more feasible)
