public class PipeClonerImpl extends PipeCloner
Since Pipes may form an arbitrary directed graph, someone needs
to keep track of isomorphism for a clone to happen correctly. This class
serves that role.

TubeClonerWhen your pipe has references to other pipes, it's particularly important to call this method before you start copying the pipes you refer to, or else there's a chance of inifinite loop.
add in class TubeClonerpublic <T extends Tube> T copy(T t)
TubeClonerTube#copy(TubeClonerImpl) implementation
to copy a reference to another pipe.
This method is for Tube implementations, not for users.
If the given tube is already copied for this cloning episode, this method simply returns that reference. Otherwise it copies a tube, make a note, and returns a copied tube. This additional step ensures that a graph is cloned isomorphically correctly.
(Think about what happens when a graph is A->B, A->C, B->D, and C->D if you don't have this step.)
