Animal class

Animal class is the parent/base class for Tiger class, Penguin class, and Turtle class.

Animal class
- Protected
    - Static constexpr double base food cost
    - Age, babies, starting cost, food cost, payoff
- Public
    - Setters
        - Set age, babies, starting cost, food cost, payoff
    - Getters
        - Get age, babies, starting cost, food cost, payoff
    - Other functions
        - Animal aging function
    - Default constructor
    - Custom constructor that takes in an integer age

NOTES:

    Age
    Adult if age >= 3 days
    Baby if age < 3 days
    ** babies start at 0 days old
    ** newly bought animals start at 1 day old
    *** Dead animals will be set -1 days old
