Printing events

• Understanding the event flow in asynchronous programs has always been a challenge.
• It is particularly the case in the context of Combine, as chains of operators in a publisher may not all emit events at the same time.
• Combine provides a few operators to help with debugging your reactive flows. Knowing them will help you troubleshoot puzzling situations.
