Default implementation for a configuration root.

If you think you want to subclass this, you're probably wrong. Note that you can have whatever setup code you want, called automatically from .ini files loaded by this class. We recommend you try that approach first.

nameNotFound (
        self,
        root,
        name,
        forObj,
        default=NOT_GIVEN,
        )

noMoreValues (
        self,
        root,
        configKey,
        forObj,
        )
