-
-    Abstract:
-
-        This module contains an implementation for KWorkItem.
-
-        A KWorkItem inherits from CRef and is reference counted.  The object 
-        cannot be destroyed until all references are released.  This includes
-        the reference held when the workitem is in flight.  This allows you 
-        to store the workitem in an object that has a lifecycle shorter than
-        the parent device object.
-
-    History:
-
-        created 5/30/2014
