[vtkusers] How to use vtkDataObjectReader in C++

[Jothybasu Selvaraj]

I don't think ReadFieldData returns anything.

Instead you should be using do_reader->GetOutput()->GetFieldData(); (after
calling ReadFieldData())

I suggest you to instantiate the class like this

vtkSmartPointer<vtkDataObjectReader> do_reader =
 vtkSmartPointer<vtkDataObjectReader>::New();
