[vtkusers] How to use vtkDataObjectReader in C++

[David E DeMarle]

You need to use New() and Delete() for to create vtkObjects. This
makes it possible for VTK to reference count everything to help ensure
objects are not accessed after deletion or deleted more than once.

Consider using smart pointers as well because then you don't generally
have to Delete() what you New() and are less likely to leak memory.
