/**
* @class vtkMNITagPointReader
* @brief A reader for MNI tag files.
*
* The MNI .tag file format is used to store labeled points, it can
* store either one or two point sets. All point sets must have the
* same number of points and they will share the same labels. This
* file format was developed at the McConnell Brain Imaging Centre at
* the Montreal Neurological Institute and is used by their software.
* The labels are stored as a vtkStringArray in the PointData of the
* output dataset, which is a vtkPolyData.
* @sa
* vtkMINCImageReader vtkMNIObjectReader vtkMNITransformReader
* @par Thanks:
* Thanks to David Gobbi for contributing this class.
