Create a namespace for augmenting existing modules

[obriencj]

Create an empty namespace package sibilant.site

Example 1, a sibilant.site.requests module might provide macros for dealing with the requests library.

Example 2, sibilant.site.argparse might define a DSL for specifying command-line arguments.

[obriencj]

Use a native namespace package as per PEP-420
and the Packaging Namespace Packages Guide

Thus a directory sibilant/site/

This can contain .lspy and .py files (just not an init.lspy or init.py) named after existing packages. It can also be added to by separate eggs.

However, until such time as I have at least a single augmented module, setuptools doesn't support completely empty PEP-420 namespaces.
