// 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.

//
