-
-        This file contains the implementation of the CImageHardwareSimulation 
-        class.
-
-        This is a specialization of CHardwareSimulation that provides photo-
-        specific metadata and implements specialized functionality for photo, 
-        photo sequence and variable photo sequence.
-
