Program to determine if a year is a leap year.

To determine if a year is a leap year, follow these steps:
1.   If the year is evenly divisible by 4, go to step 2. Otherwise, go to step 5.
2.   If the year is evenly divisible by 100, go to step 3. Otherwise, go to step 4.
3.   If the year is evenly divisible by 400, go to step 4. Otherwise, go to step 5.
4.   The year is a leap year (it has 366 days).
5.   The year is not a leap year (it has 365 days).

to take in a date for range
1.  take a starting date
2.  take a ending date
3.  collect the dates between and including starting date and ending date
4.  display the leap years between theses dates

Wow - you're totally going all out by making this object oriented. Cool!
