        *              interface implementations can only have two signatures for

        *              NewL:

        *               - 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.

        * @param aCtx is the session context that will be accessed and

        * modifications on the layer of the session construction, validation,

        * or some other, focused area that the handler was intended to take
