//  The CVisList wraps arounda  CList, addition a few extra features,
//  to manage a list of CVisInterace Pointers.  It's imporant to note
//  that it directly deals with the pointers, not copies.  If a pointer
//  is deleted outside of the list, the node will be invalid.

// Description: List of CVisInterface Pointers.  Handy to use to keep a 
//              list of 'em.  This is just a CList with a few additional
//              methods to help use the list.
//
//     Methods
//          of  
//    Interest: operator += (CVisInterface *) 
//                 - Add a Node to the list.
//
//              operator -= (CVisInterface *)
//                 - Remove the passed node from the list.
//
//              RemoveAll()
//                 - Delete ALL pointers in the list, then delete the list
//                   (If you need keep a pointer, save it, use -= to remove
//                    it from the list).
//          
//              Find(CVisInterface *)
//                 - Get the position of the passed pointer in the list.
