Detailed Description

a CacheManager - the menu system for interacting with squid. This is currently just an adapter to the global cachemgr* routines to provide looser coupling between modules, but once fully transitioned, an instance of this class will represent a single independent manager. TODO: update documentation to reflect the new singleton model.
