[ITK] [ITK-users] Pointers and New()

[Matt McCormick]

Hi Abdul,

Welcome to ITK!

Yes, we always want to use ::New(), which returns ITK SmartPointer's
[1] since this is used by the reference count kept in all ITK Object's
[2]. This is described in more detail in the ITK Software Guide [3].

Hope this helps,
Matt
