Field never used in core

[gurghet]

The field below, while logically belongs to core, it's never used by it and only used by the modules. This is just code smell and not a real problem but might indicate there is a better way to structure the code. https://github.com/laserdisc-io/tamer/blob/4af203cff31c36e41b1cbca507c17ca3a1bc4b4f/core/src/main/scala/tamer/Setup.scala#L12 It means it's possible to do things like override Setup and

override val recordKey: (State, LastAlertTime) => LastAlertTimeKey = ???

and make the code still work because you are using a different way to create your record key.
