about itkScalar and itkVector

[Bill Hoffman]

Hi, 

The use of ::Pointer is required.  This is to avoid leaks and crashes.

For example:

itkFoo<bar>* i = itkFoo<bar>::New();
i->Print();

would crash because the value returned by New would be put
into a temporary ::Pointer then converted to a *, then the
temp would go away leaving i pointing to deleted memory.
I have just checked in a change that will give a syntax
error in the above code.

We are looking into the itkImage<int, 3> issue.  Will will get
back to you tomorrow.
