No support for inhertiance or generic parameters about mockgen

[thomas-girotto]

Yep, you're right, i didn't think about testing generic methods while developping my lib, and i realized it doesn't work some weeks ago while trying to use it on another project.

I'm working to add support for them, though i still didn't find the right way to do it yet. Unless i'm missing some clever way to do it, it requires quite a lot of changes...

As for inheritance, thanks for the feedback, i wasn't aware it doesn't work either. This use case should be a lot easier to handle though.

Thanks for the first issue :)
