@jessycatterwaul, @catie, why is animateIn() a method of a UIView meanwhile ainmateOut() a func within a LessonViewController?

@catie, @jessycatterwaul, please explain
completion: handleCompletion.map { handleCompletion in
{ _ in handleCompletion() }
in animateIn() a bit more detailed. It is unclear for me now. =(

The first step to understanding it is to get comfortable with Optional.map. Let me know if you have any questions about that method in particular, and we’ll go from there!
