 * @class   vtkMultiNewickTreeReader
 * @brief   read multiple vtkTrees from Newick formatted file
 *
 * 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.
