[vtkusers] Memory mangement in vtk

[Marco Nawijn]

You can however make VTK a little more C++ 11-ish with simple helpers. For
example I use the following template to make construction of VTK objects a
little less verbose:

template <typename T>
vtkSmartPointer<T> make_shared_vtk()
{ // Helper to reduce boilerplate code for creating VTK objects
  return vtkSmartPointer<T>::New();
}

As an example, the code for creating a vtkImageData object is then:

auto image = make_shared_vtk<vtkImageData>()

Regards,

Marco
