IPFIX implementation for Python 3.3.

This module provides a Python interface to IPFIX message streams, and provides tools for building IPFIX Exporting and Collecting Processes. It handles message framing and deframing, encoding and decoding IPFIX data records using templates, and a bridge between IPFIX ADTs and appropriate Python data types.

WIP: porting to Python 2.7. New dependencies:

• pip install functools32
• pip install py2-ipaddress
• pip install pytz

New test dependencies:

• pip install doctest-ignore-unicode
