         *              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.
