[Paraview] Setting a single meta data value to a PolyData object

[Berk Geveci]

Yes. Create a new data array (with the appropriate name) and add it to
the FieldData. Something like:

vtkFloatArray* newarray = vtkFloatArray::New();
newarray->SetName("foo");

vtkFieldData* fd = vtkFieldData::New();
fd->AddArray(newarray);

output->SetFieldData(fd);

newarray->Delete();
fd->Delete();

The field data is automatically propagated by the pipeline and will be
accessible to all filters downstream.
