shared_ptr has some magic so it deletes through the same type of pointer that 
was passed to its constructor, which can eliminate the need for virtual 
destructors in some cases.  Notice how the shared_ptr constructors take the 
pointer as a template parameter of the constructor, as opposed to just using 
the template type of the shared_ptr itself.
