/**
* Register Handling Events
*
* Interface used by various authorities to register handling events for cargos. This would be a
* separate interface not coupled to the booking system, but for testing convenience it is integrated
* with Booking and Tracking.
*
* Tip: try open the Event Registration window side-by-side to a Cargo details window for a specific cargo.
* Then register events for that cargo and here and update the details window to see the progress. You can
* also then in the details window see what event is expected next...
