Add a section to explain how to locally test a packaged Python library

@@ Line 15: / Line 15: @@
 You can now run <code>nix-shell</code> and it will drop you in a shell similar to the <code>python setup.py develop</code> mode which uses the local code in <tt>./path/to/source</tt> as input. <code>propagatedBuildInputs</code> will contain the packages you  need in your project.
 After you've finished developing you can replace the relative path with <code>fetchFromGitHub { ... }</code> or <code>[https://github.com/NixOS/nixpkgs/blob/master/pkgs/build-support/fetchpypi/default.nix fetchPypi] { ... }</code>.
