*
* Application wiring for Shrine, in the base, non-HMS case. All vals are protecetd, so they may be accessed,
* in subclasses without ballooning this class's public API, and lazy, to work around init-order surprises when
* overriding vals declared inline. See

* https://stackoverflow.com/questions/15762650/scala-override-val-in-class-inheritance
*
* among other links mentioning val overrides, early initializers, etc. -Clint
