Object Oriented Design

Example: An Educational Game (Class and Function Comments)

Before reinventing the wheel, determine if you can use the Time class that is part of the book before designing a new class.
To use the Time class from the book, you must set seconds to zero. (Seconds has no use in our game).
To see whether two times are identical, check whether there are zero seconds from the first time to the second time.
```
time1.seconds_from(time2) == 0
```
