EOW.

You're extending the wrong identifier; when you do:

> from de.ikv.grasshopper.agent import MobileAgent

the identifier "MobileAgent" is brought into your namespace,
there's no need to use "de.ikv.grasshopper.agent.MobileAgent",
because you didn't import the whole module, only a single
identifier from within.

I know I shouldn't say this, but reading the docs will help
you.
