Exercise

1. Humans initialize with a first_name and last_name.

2. Humans initialize with an _age of 0. This will be a property (age) later.

3. Give humans a __repr__ that adequately shows their characteristics. You decide what this looks like.

4. Give humans a method say_full_name which returns their concatenated first_name and last_name.

5. Give humans a method happy_birthday which increments that human's age by 1.

6. Give humans a property age. When someone attempts to set a human's age directly it instead doesn't change and returns the string "Quit lying about your age!".
