[Insight-developers] SmartPointers

[kent williams]

If you assign the output of a filter to a smart pointer, e.g.

ImageType::Pointer ip = filter->GetOutput();
filter = FilterType::Pointer(); // force filter deletion by assigning empty
smart pointer.

the pointer Œip¹ should still point to a valid image, since when the filter
is deallocated, Œip¹ still holds a reference.
