Assignment directories

When turning in your assignments, please remember to follow the directory structure we've specified in the assignment. That means turning in assignment2 in the folder `assignment2`.

In the end of the course, your repo should have five directories in the top level: `assignment1`, `assignment2`, etc. up to 5.

Also make sure to push to the repo on the IN3110 organization (`github.uio.no/IN3110/IN3110-yourname`), _not_ your personal fork (`github.uio.no/yourname/IN3110-yourname`). We cannot grade your personal copies.
