class to read any type of vtk data object
vtkGenericDataObjectReader is a class that provides instance variables and methods to read any type of data object 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 return 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.

This can be overridden by a subclass to create an output that is determined by the file being read.
If the output is known at compile time, it is easier to override FillOutputPortInformation() to set vtkDataObject::DATA_TYPE_NAME(). The subclass should compare the new output type with the type of the currentOutput argument and return currentOutput without changing its reference count if the types are same.
