Split boiler-plate connection code into a separate file since the basic sample already covers this aspect. The `app.go` file now only presents the main application code, making it much easier for readers to view.
Also changed the event replay code to use a different style of reading from the real-time eventing example, demonstrating the use of timeouts while reading events we expect to arrive quickly, and avoiding any possibility of the main application execution hanging indefinitely.
