You are given a minimal set of unit tests. The tests are not at all exhaustive. Feel free to modify or add your own tests.

You are also given a main method. The main method should output the following:

r1                          : |?|?|?|?|?|?|?|?|?|

r2                          : |5|9|1|4|8|6|3|2|7|
r2.get(3)                   : 4
r2.isValid()                : true
r2.set(0, Digit.get(9))     : |9|9|1|4|8|6|3|2|7|
r2.isValid()                : false
r2.safeGetRow()             : [9, 9, 1, 4, 8, 6, 3, 2, 7]

r3                          : |?|9|1|4|8|6|3|2|?|
