+ *  itk data pipeline to a VTK datapipeline.   
+ *
+ *  This class puts together an itkVTKImageExporter and a vtkImageImporter.
+ *  It takes care of the details related to the connection of ITK and VTK
+ *  pipelines. The User will perceive this filter as an adaptor to which
+ *  an itk::Image can be plugged as input and a vtkImage is produced as 
+ *  output.
