beginner questions on embedding/extending python with C++

[Qun Cao]

Thanks Diez,
It is a good relief that I only need to wrap the classes I need.  I
decide to try Boost first because it seems to have a wider audience
than SIP, but I would definately look into SIP if I want to do Qt
development in the future.
