   <abstract>
   This class serves as a container for a nib file.  It's possible 
   to load a nib file from a URL or from a bundle.   Using this 
   class the nib file can now be "preloaded" and instantiated 
   multiple times when/if needed.  Also, since it's possible to 
   initialize this class using a NSURL it's possible to load 
   nib files from remote locations. 
   <b/>
   This class uses: NSNibOwner and NSNibTopLevelObjects to allow
   the caller to specify the owner of the nib during instantiation
   and receive an array containing the top level objects of the nib
   file.
