   CacheFile - Simple wrapper class for opening, generating and whatnot
   
   This class implements a simple 2 line mechanism to open various sorts
   of caches. It can operate as root, as not root, show progress and so on,
   it transparently handles everything necessary.
   
   This means it can rebuild caches from the source list and instantiates
   and prepares the standard policy mechanism.
