/**
* @class vtkDataSetReader
* @brief class to read any type of vtk dataset
*
* vtkDataSetReader is a class that provides instance variables and methods
* to read any type of dataset in Visualization Toolkit (vtk) format. The
* output type of this class will vary depending upon the type of data
* file. Convenience methods are provided to keep the data as a particular
* type. (See text for format description details).
* The superclass of this class, vtkDataReader, provides many methods for
* controlling the reading of the data file, see vtkDataReader for more
* information.
* @warning
* Binary files written on one system may not be readable on other systems.
* @sa
* vtkDataReader vtkPolyDataReader vtkRectilinearGridReader
* vtkStructuredPointsReader vtkStructuredGridReader vtkUnstructuredGridReader
