Subject: python/python-apt.h: Introduce the C++ API

The C++ API provides support for creating Python objects from C++ objects
given by pointer or reference (depending on the implementation of the Python
object) and for retrieving the underlying C++ object from the Python object
and for checking the type of the Python object.
