// .NAME vtkMNITagPointWriter - A writer for MNI tag point files.
// .SECTION Description
// The MNI .tag file format is used to store tag points, for use in
// either registration or labelling of data volumes.  This file
// format was developed at the McConnell Brain Imaging Centre at
// the Montreal Neurological Institute and is used by their software.
// Tag points can be stored for either one volume or two volumes,
// and this filter can take one or two inputs.  Alternatively, the
// points to be written can be specified by calling SetPoints().
// .SECTION See Also
// vtkMINCImageReader vtkMNIObjectReader vtkMNITransformReader
// .SECTION Thanks
// Thanks to David Gobbi for contributing this class to VTK.
