DESCRIPTION
This trivial example shows how to publish notification channel events in
Python using the standard FRIDGE::temperatureDataBlockEvent example. In particular,
50 events are sent, pausing for one second between each event.

WHAT CAN I GAIN FROM THIS EXAMPLE?
- Supplier class usage.
- Publishing events.
