/**
* This class handles parking costs for different types of parking activities.
* There are still things to refactor:
* - There are lots of magic numbers.
* - The method handleEvent(PersonEntersVehicleEvent event) is too long.
* - Helpful comments are missing.
* At least, there is a test class for this class. (paul april 2024)
