 *
 * vtkMultiNewickTreeReader is a source object that reads Newick tree format
 * files.
 * The output of this reader is a single vtkMultiPieceDataSet that contains multiple vtkTree
 * objects. The superclass of this class, vtkDataReader, provides many methods for controlling the
 * reading of the data file, see vtkDataReader for more information.
