Create a class Date that can perform the following operations on a date:
- Set/Return the Month
- Set/Return the Day
- Set/Return the Year
- Whether the year is a leap year.
if the year number isn't divisible by 4, it is a common year;
otherwise, if the year number isn't divisible by 100, it is a leap year;
otherwise, if the year number isn't divisible by 400, it is a common year;
otherwise, it is a leap year.
- Return the number of days in a month
April, June, September, November has 30 days otherwise 31 except for Feb (refer to leap year)
- Print the month in string format followed by the date and year
