Swap '2016' for '1996' to stop faulty logic from passing unit test [This leap solution](http://exercism.io/submissions/7ef5b0ab93b540f79cdee9f153e0a21c) should not pass the unit test, since it checks whether `year % 100` and `year % 400` are equal in order to tell whether the year it has been passed is a leap year. This works for 2016 because `2016 % 100` and `2016 % 400` both evaluate to 16. 1996, another leap year that is divisible by 4 but not 100, does not have this property and, under that solution, would falsely not be classed as a leap year. 2017-10-24 14:44:48 +01:00			`self.assertIs(is_leap_year(1996), True)`
