Provides a caching wrapper to be used in place of large structures. This should be extended by systems that need to cache large amounts of data to calling functions. These structures can become very large, so this class is used to allow different strategies to be used for caching internally (lazy loading, building caches over time etc.). This can dramatically reduce the amount of data that needs to be loaded from cache backends on each request, and memory usage from static caches of that same d
