Documentation

The documentation for extending new types using a C extension just uses Py_SETREF and Py_NewRef with no extra clarification as to what those functions do. It'd be nicer and more convenient if they were explained on-the-spot instead of having to search for it in the docs. They are also not explained in the previous topic (that explains Py_INCREF and Py_DECREF) and the other topics thereafter.
