 This example shows how you can perform an expensive calculation on the main thread in a non-blocking fashion. It uses `yield()` for every step in the calculation so that other work, like drawing the UI, can be performed
 on the main thread. It is more a "showcase" rather than a use case for a real application, because of performance reasons you should always perform expensive calculations on a background thread (See UseCase#10).
