copy constructor not dealing with contained references properly.

[pahjbo]

Copy constructors are not copying references by design - however, in the case of contained references it might be appropriate to copy references. This is complicated by the fact that whether the copy is appropriate depends on where the original copy started.

see also #41 where the rules for "contained" references need to be defined.

think that release 0.4.4 contains a fix for this - however keeping issue open as might change the API depending on experience of use.

model.createContext();
ATest atestprime = new ATest(atest);
atestprime.updateClonedReferences();
