Tuttask example problem

This is an example problem for the Berlyne platform.

See wiki page for the tutorial.

To use this in Berlyne, just do a:

git clone https://github.com/rugo/tuttask.git

in your Berlyne deployment path (VAGR_DEPLOYMENT_PATH in settings.py).
