   Acquire Item - Item to acquire

   When an item is instantiated it will add it self to the local list in
   the Owner Acquire class. Derived classes will then call QueueURI to 
   register all the URI's they wish to fetch for at the initial moment.   
   
   Two item classes are provided to provide functionality for downloading
   of Index files and downloading of Packages.
