/**
 * @class   vtkMINCImageWriter
 * @brief   A writer for MINC files.
 *
 * MINC is a NetCDF-based medical image file format that was developed
 * at the Montreal Neurological Institute in 1992.
 * The data is written slice-by-slice, and this writer is therefore
 * suitable for streaming MINC data that is larger than the memory
 * size through VTK.  This writer can also produce files with up to
 * 4 dimensions, where the fourth dimension is provided by using
 * AddInput() to specify multiple input data sets.  If you want to
 * set header information for the file, you must supply a
 * vtkMINCImageAttributes
 * @sa
 * vtkMINCImageReader vtkMINCImageAttributes
 * @par Thanks:
 * Thanks to David Gobbi for writing this class and Atamai Inc. for
 * contributing it to VTK.
