It is not enough to pass the address of a C++ object. You have to make
each of it's methods available individually to Python, i.e. write a
wrapper function for each of them and make it known to the
interpreter. The online docs describe how this is down.
There is also a program called Swig (see www.swig.org) which can do
that almost automatically for you.
