In this video we make our first class and Chili teaches us about the birds and the bees and the static constexpr.

== Concepts Taught ==
* Creating a <code>class</code>
* <code>public</code> vs. <code>private</code> access
* <code>static</code> member variables
* <code>constexpr</code> variables

== Homework ==
Make the Dude entity into a <code>class</code> as well. It's up to you to decide what member functions you should give it. Might want to add another function to <code>Poo</code> as well (hint hint hint!).

The solution is given in [https://youtu.be/b4FjV2R9jy0 this video].
