|Freezable<T extends Freezable>||
Auto-serializer interface using a delegator pattern (the faster option is to byte-code gen directly in all Iced classes, but this requires all Iced classes go through a ClassLoader).

Jobs are used to do minimal tracking of long-lifetime user actions, including progress-bar updates and the ability to review in progress or completed Jobs, and cancel currently running Jobs.
