Initialize() implementation.
This method is called only once by Initialize(). If the user calls Initialize() multiple times, DoInitialize() is called only the first time.
Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject() and AggregateObject() from within this method.
