[py-dev] Local import

[Joan Miller]

I was wrong since that it isn't necessary to import the source from
tests. It's better to use 'python setup.py develop' because it manages
well this problem.

"When you're installing a distribution, you can install it in develop
mode instead with python setup.py develop. Using this mode, a special
link file is created in your site-packages directory. This link points
back to the current folder or 'root package'. Any changes you make to
the software here will be reflected immediately without having to do
an install again.

When you're ready to install for good do a real install."
