There are several improvements in language mappings, as well as cleanup of the code for python2.2 (Py_ssize_t handling) and MacOS 10.3. Additionally, there are code cleanups (removing use of CINT internals) that should be fully transparent to the end-user.

The language mapping improvements are:

• Abstract classes can no longer be instantiated (__init__ will raise an exception)
• Looping over empty STL(-like) containers will yield an immediate StopIteration
• Unknown& is favored over Unknown* in function overloading
• Implemented unary-, unary+ (__neg__ and __pos__)
• Mapped operator bool() to __nonzero__
• Support for templated member functions
• Implemented __setitem__ for unsigned int& and unsigned long& returns
