Create sets of toggle-able choices with ValidatedChoiceList. This is a feature-flag-style setting, poll for active features using List#contains.

This validation is a List<T>, where T is your choice type. Like ValidatedList, this implements List, so can be used directly for list operations.

Easily create a choice list using toChoiceList in ValidatedList / Set / Choice.

ValidatedChoiceList<String> enabledFeatures = ValidatedList.ofString(
		"dev_mode", "logging", "fail_fast", "compatibility_mode" //the total list of choices/features
).toChoiceList(
		listOf("logging") //the enabled-by-default features
);

The in-GUI popup with the available choices, each in an enabled or disabled state. Clicking on a choice flips its state.
