// Purpose:     An SList is a LISP like list of Items.
//              An SList is :
//                . Empty.
//                . Or it has a Value and a  Tail  which is an other SList. 
//              
//              The Tail of an empty list is an empty list.
//              SList are  shared.  It  means   that they  can  be
//              modified through other lists.
//              SList may  be used  as Iterators. They  have Next,
//              More, and value methods. To iterate on the content
//              of the list S just do.
//              
//              SList Iterator;
//              for (Iterator = S; Iterator.More(); Iterator.Next())
//                X = Iterator.Value();
//            
//              Memory usage  is  automatically managed for  SLists
//              (using reference counts).
//             
// Example:
//              If S1 and S2 are SLists :
//              if S1.Value() is X.
//              
//              And the following is done :
//              S2 = S1;
//              S2.SetValue(Y);
//            
//              S1.Value() becomes also Y.   So SList must be used
//              with   care.  Mainly  the SetValue()    method  is
//              dangerous. 
//
