Browse Source 
* Add named caches and apply to NonInvalidingUnboundCache and all usages.

* Add named caches and apply to NonInvalidingCache and all usages.

* Add named caches and apply to NonInvalidingWeightBasedCache and all usages.

* Move NamedCache to core/internal

* Remove type `NamedCache` and `NamedLoadingCache`

* Suppressed 'name not used' warning, added comment, and fixed generic parameters on the buildNamed functions.

* Use `buildNamed` in all caffeine instances in production code. Not using it for caches that are created in test code.

* Add checks for the cache name

* Formatting
