Python: Test framework should be updated.

There should be more cases as this:

*filling box while eyes closed*
[1 1 0 1 1 1]
[0 0 1 1 1 1]
[1 2 2 0 1 1]
[1 2 1 1 2 1]
[2 0 2 1 1 1]
[1 2 1 2 1 1]
[0 1 0 1 1 2]
[1 1 1 1 1 1]
Rot time should be -1

The description should state that here a "neighbor" is in the sense of von Neumann neighborhood (no diagonal). It's impossible to know it from the example and the unique test case.

The description should state weither all lists have the same length or not (from the only example/basic test, one may suppose it is the case).

Thanks for the kata. Maybe it could be extended by adding the variable of direction being CW or CCW possible paths.
