setuptools extension for building non-Python Dynamic Shared Objects

Building non-python shared libraries (eg. libY.so, libY.dylib, or Y.dll) for inclusion in a Python Wheel.

This setuptools extension provides at alternative to bundling externally built libraries in Python Wheel packages. This replaces an external build system (eg. Makefile), allowing non-python libraries to be built from source within a python ecosystem.
