A macOS screensaver.
To test the screensaver, you can simply run the Target ScreenSaverTest.
Build the target DancingBoids, then open the artifact DancingBoids.saver.
The screensaver consists of multiple animations that are playing,
being randomly every now and then.
If you want to add a new animation,
you can create an implementation of ScreenSaverViewDelegate
and add the type of that delegate
to screenSaverDelegates in DancingBoidsView.
You may use the flockingbird library (import Flockingbird) to create boid animations.
For an example of the above, see FlockingScreenSaverViewDelegate.
