Return a shared_ptr<TO_TYPE> object sharing ownership of the same object as the specified source shared pointer to the (template parameter) FROM_TYPE, and referring to dynamic_cast<TO_TYPE*>(source.get()). If source cannot be dynamically cast to TO_TYPE *, then an empty shared_ptr<TO_TYPE> object is returned.
