Add Python support

[GaryHilares]

Problem

Sometimes I want to take some information from C++ to another Python program. However, I have that information in GSS, and Python does not support GSS. In consequence, I have to manually convert GSS to XML or JSON and this is very impractical.

Describe

I would like a Python module that allows reading GSS from Python. It would be nice if it includes all functions that are also included in C++, but at least a reader module should be added.
