Team coding dojo 2.2

Today was the second time I organized a dojo in my new team. We did the MineSweeper and it turned out interesting as usual. The highlights today was how the design got pushed in one direction by a typo in a test. The typo made us expose the internal representation of an mine field before the sweep which I don't see that often. Also the use of enums was definitely the result of having a specific person taking the keyboard at a specific time. Will be fun to see what we can do with the MineSweeper the next time.
