GenericAdjustPropertySetterFactory
class GenericAdjustPropertySetterFactory(adjust: AdjustInstance) : AdjustPropertySetterFactory, FallbackFactory(source)
Registers any property as an Adjust global callback parameter, appended to the callbacks Adjust fires for later sessions and events. Claims everything, so it belongs last in a chain.
Adjust draws no distinction between an attribute of the session and one of the person, so this covers UserProperty too.
There is no generic Adjust event factory: an event reaches Adjust only with a token.
