Interface Summary

Interface	Description
Action	This interface represents any piece of code that takes no input and produces no output but may fail.
Copyable<Self>	Implementing objects must be able to provide copies of themselves.
JsonSerializable	This interface prescribes implementing instances to be able to provide itself as a WayangJsonObj.
JsonSerializer<T>	Alternative to JsonSerializable: Externalizes serialization logic.
Logging	Provide logging via Logger.
ReferenceCountable	This interface provides a reference-counting scheme, e.g., to manage allocated external resources.
