LAB0 and HA0 results

We checked the submissions for the HA0 phase (that qualifies as the LAB0 session). We accepted all submission.

IMPORTANT: For some students it was not easy to check whether he or she contributed to the tasks, e.g. their output was a late comment to an issue. For the subsequent phases please be sure that everyone has a tangible contribution to the team's work that is visible in the GitHub repository (e.g. commits to the repository, edits in the wiki page, meaningful review comments on issues).
