Missing files - simulation can't be started

I recently started a reorganization of the repository and the current version is broken (unavailable outside packages are necessary). Unfortunately, I can't say when that might get fixed. In the meantime, check out an older version when everything was still in the same place: https://github.com/mkrizmancic/sphero_formation/tree/0ac14aad3dd1a0af26f191c017e213279eebd52e
