A simple demonstration of how you might "extend" Kotter using extension methods, so you, too, can create functions like
input, offscreen, aside, onKeyPressed, etc.
Doing this requires understanding some implementation details underneath Kotter, specifically lifecycles, various scopes, and Kotter's thread-safe, lifecycle-aware datastore, which is explained in more depth in the README. Think of this example like a code companion for that section.
