+ *  VTK data pipeline to an ITK datapipeline.
+ *
+ *  This class puts together an itk::VTKImageImport and a vtk::ImageExport.
+ *  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
+ *  a vtkImageData can be plugged as input and an itk::Image is produced as
+ *  output.
