From https://github.com/smartprix/sm-utils/pull/40#pullrequestreview-187416360 * Docs need to be made regarding all the choices of localCache, LRU, differences for pika, etc. separately than the jsdoc. * jsdoc is not updated. * No tests separately for LRU. * Types need to be updated. #37 * Make CLI for benchmarking? (Might not be necessary, because it includes many extra dependencies)
