ISO Standards Setup

Standard setup.py file which is used to package and distribute a Python package
with Distutils so that it can be published to a PyPI server.  This file
belongs in the root directory of a project repository.  This is an example that
uses some basic options which are available for the setup of a PyPI package. It
also reads and gathers example dependencies for a package.

See:
    https://pythonhosted.org/setuptools/setuptools.html for more details.
