/** \class ImageToVTKImageFilter
 * \brief Converts an ITK image into a VTK image and plugs a 
 *  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.
