Clone

The Clone application is one of the HELICS apps available with the library Its purpose is to provide a easy way to clone a federate for later playback It acts as a federate that can "capture" values or messages from a single federate It also captures the interfaces and subscriptions of a federate and will store those in a configuration file that can be used by the Player. The clone app will try to match the federate being cloned as close as possible in timing of messages and publications and subscriptions. At present it does not match nameless publications or filters.
