Hello everybody,
we figured out that the mitkBaseData class misses a method to produce a deep 
copy. We have added now such a method (Clone()) for the mitkBaseData class and 
some of its subclasses (mitkImage, mitkSurface, mitkPointSet, 
mitkUnstructuredGrid and mitkContour). Although we enhanced the unit tests as 
well, we urge you all to report any bugs resulting from this feature.
For all that need a clone method in own subclasses of mitkBaseData, the 
implementation is pretty easy:

1.       Include mitkCommon.h, if it is not included anyway

2.       Add mitkCloneMacro(Classname) in your header file

3.       Enhance the class by a copy constructor (cf. mitkSurface...)

Hope you all will enjoy this new feature!

Best regards

Sven
