   Package Manager - Abstacts the package manager

   Three steps are 
     - Aquiration of archives (stores the list of final file names)
     - Sorting of operations
     - Invokation of package manager
   
   This is the final stage when the package cache entities get converted
   into file names and the state stored in a DepCache is transformed
   into a series of operations.

   In the final scheme of things this may serve as a director class to
   access the actual install methods based on the file type being
   installed.
