         * For now this class is only useful as a demonstration of the 
         * IScriptConsoleCodeGenerator and related classes. Dragging anything
         * other than a toplevel node out of the Variables view does not produce
         * anything interesting.
         * 
         * TODO? Write code that can determine a full access to this variable
         * name e.g. if a list called name is in the variables view and the
         * index 0 is dragged into the console, the ideal thing to return here
         * is "name[0]". At the moment I don't think enough information is
         * returned from pydevd_vars to determine the difference between types
         * of objects. Doing this is possible for simple cases, but for all
         * cases it may be difficult or impossible. Consider, for example, dict
         * entries which need resolving by id(). Perhaps an access to a pydev
         * function, so if you drop a dict key you get a line like this:
         * pydevd_resolver.DictResolver().resolve(dict_name, 'a (12345678)')
         * Of course for a complex hierarchy of objects the line would be
         * quite unreadable.
