This is an example of using Sine behavior to make truly ease-in and ease-out motion. This is not a perfect solution, rather a demo of a concept of a feature I've needed but couldn't find anywhere.
I am aware of lerp(), but I am personally couldn't find a way to use it for ease-in motion (from zero velocity to X).
