''' How to Install

The easiest solution it so install via PyPI:

    pip install mazelib

But if you know setuputils/distutils, you can build locally:

    pip install -r requirements.txt
    python setup.py install

To run the test suite any of the following will work:

    python setup.py test
    nosetests test/
    pytest test/
    make test
