I've been playing around with the idea of a user-friendly way to make a toggle-able animation, meaning the user creates a single animation object, and when that object is played, the animation either plays forward or backward, depending on the animated node's current position or animation status. If the animation is played while it's already running, it would stop and then play in reverse from the current position.

I tried a few different methods, but they all were unsuccessful or unreasonable one way or another. After this experimentation I realized that the best solution would be to add a reverse function to _Animation that would basically stop the animation if running and then play in reverse.
