+* Description: Platform agnostic Qt wrapper class for controlling display
+*              power save mode. The power save mode gets actually activated
+*              only on Symbian environment; in other environments the provided
+*              functions do nothing.
+*              The use of Symbian display power save API has been wrapped with
+*              client-server pair because HbDeviceDialogs don't have enough
+*              capabilities to call that API directly.
