// .NAME vtkDataObjectReader - read vtk field data file
// .SECTION Description
// vtkDataObjectReader is a source object that reads ASCII or binary 
// field data files in vtk format. Fields are general matrix structures used
// represent complex data.

// .SECTION Caveats
// Binary files written on one system may not be readable on other systems.

// .SECTION See Also
// vtkFieldData vtkFieldDataWriter
