/**
 * @class   vtkMINCImageAttributes
 * @brief   A container for a MINC image header.
 *
 * This class provides methods to access all of the information
 * contained in the MINC header.  If you read a MINC file into
 * VTK and then write it out again, you can use
 * writer->SetImageAttributes(reader->GetImageAttributes) to
 * ensure that all of the medical information contained in the
 * file is tranferred from the reader to the writer.  If you
 * want to change any of the header information, you must
 * use ShallowCopy to make a copy of the reader's attributes
 * and then modify only the copy.
 * @sa
 * vtkMINCImageReader vtkMINCImageWriter
 * @par Thanks:
 * Thanks to David Gobbi for writing this class and Atamai Inc. for
 * contributing it to VTK.
