         *              interface implementations can only have two signatures for
         *              NewL:
         *               - NewL without parameters (used here)
         *               - NewL with TAny* pointer, which may provide some client
         *                 data
         *
         * Returns:    Instance of this class.
         *
         * Note:       The interface, which is abstract base class of this
         *             implementation, also provides NewL method. Normally abstract
         *             classes do not provide NewL, because they cannot create
         *             instances of themselves.
