Manage the setup, teardown, and caching of objects of type V safely in a multithreaded environment.

The user provides the setup and teardown logic along with a maxCacheSize, and CachedFactory provides instances of V as requested using the withValue method. These instances are automatically constructed on-demand from the give key, cached with an LRU strategy, and destroyed when they are eventually evicted

Intended for relatively small caches approximately O(num-threads) in size that will typically get used in a build system, not intended for caching large amounts of entries
