交作业，在学校里上算法课，用这个放松一下。

之前那个忘记test isLeapYear了，补上

hmw2 完成

算difference那里比较困难
还有之前识别日期格式不知道有matches和split这两个function，还是参考了github才做出那一部分的

交作业了，帖子里的很过hint相当有用。特别是split方法的使用。

求打分，非常感谢！

Testing constructors.

Date should be 1/1/1: 1/1/1

Date should be 2/4/2: 2/4/2

Date should be 2/29/2000: 2/29/2000

Date should be 2/29/1904: 2/29/1904

Date should be 12/31/1975: 12/31/1975

Date should be 1/1/1976: 1/1/1976

Date should be 1/2/1976: 1/2/1976

Testing the IsLeapYear function.

That 2014 is leap year should be false:false

That 1900 is leap year should be false:false

That 1600 is leap year should be true:true

That 2012 is leap year should be true:true

Testing before and after.

1/1/1976 after 12/31/1975 should be true: true

1/2/1976 after 1/1/1976 should be true: true

12/31/1975 after 12/31/1975 should be false: false

12/31/1975 after 1/1/1976 should be false: false

1/1/1976 after 1/2/1976 should be false: false

12/31/1975 before 1/1/1976 should be true: true

1/1/1976 before 1/2/1976 should be true: true

12/31/1975 before 12/31/1975 should be false: false

1/1/1976 before 12/31/1975 should be false: false

1/2/1976 before 1/1/1976 should be false: false

Testing difference.

12/31/1975 - 12/31/1975 should be 0: 0

1/1/1976 - 12/31/1975 should be 1: 1

1/2/1976 - 12/31/1975 should be 2: 2

1/2/1976 - 2/27/1977 should be -422: -422

8/31/2110 - 2/27/1977 should be 48762: 48762
