+// Description:
+// Together, these classes and the CBTPortProxy implement the 
+// State pattern.  The states themselves are implemented using 
+// the Flyweight pattern.  Each state is a Flyweight object
+// and CBTPortStateFactory is manager of these objects.  As a 
+// result of being a flyweight, no state object may have a state 
+// that can't be shared between all possible users of the state.
