+
+        This file contains the helper class CExtendedProperty and the coommon
+        base class CExtendedHeader.
+
+        CExtendedHeader provides initialization and accessor functions for
+        KSCAMERA_EXTENDEDPROP_HEADER.
+
+        CExtendedProperty provides initialization and accessor functions for
+        KSCAMERA_EXTENDEDPROP_VALUE.  
+        
+        CExtendedProperty also combines KSCAMERA_EXTENDEDPROP_HEADER and 
+        KSCAMERA_EXTENDEDPROP_VALUE into a single object for use in the
+        macros and templates used by our filter and sensor classes.
