Path - record of connectors visited during dataflow

       A  Path object stores a record of connectors that have been visited during dataflow.  Transfer functions,
       state variables, connectors, and other components can use  the  information  in  the  path  to  determine
       whether data should be transmitted, for example, to avoid circular flow.
