// Class: uniMuxCatcherTransporter 
//
// Description:
//      Coordination protocol needs to know the pointer of the
//      above mux conduit, because it needs to call mux-specific
//      methods. The pointer can't be got any other way.

// Class: uniCrossConnecter
//
// Description:

//      pfCrossConnecer class performs this task, and can still get the
//      pointer to the cc.
