'tests' directory is getting installed by the package

[SchrodingersGat]

I have found that the 'tests' directory is being installed to site-packages when installing via pip:

You can ignore certain directories in the find_packages directive:

python-barcode/setup.py

Line 8 in 0f223c0

packages=find_packages(),

e.g.

    packages=setuptools.find_packages(
        exclude=[
            'tests',
        ]
    ),
