dont give Nexus a path to a cache, give it the cache object itself. #139
Description
this simplifies the API more, and removes even the idea of pathing from that level of abstraction. for example, in lib broker, we wouldn't have to pass the path of the cache folder to nexus. instead sjust pass the cache weve already created. after all, Nexus runs Caches, not folders! if you wanted an in Memory only cache for example, whats the path to that, doesnt make any sense. remove pathing from the api level.
