* @class vtkNewickTreeReader
* @brief read vtkTree from Newick formatted file
*
* vtkNewickTreeReader is a source object that reads Newick tree format
* files.
* The output of this reader is a single vtkTree data object.
* The superclass of this class, vtkDataReader, provides many methods for
* controlling the reading of the data file, see vtkDataReader for more
* information.
* @par Thanks:
* This class is adapted from code originally written by Yu-Wei Wu.
