''' How to Install

The easiest solution it so install via PyPI:

    pip install mazelib

But you can build mazelib locally using this file.

First things first:

    pip install -r requirements.txt

To build mazelib and install the package on your computer:

    python setup.py install

To build/install locally, not system-wide:

    python setup.py install --inplace

To force all Cython code to rebuild/reinstall locally:

    python setup.py install --inplace -f

To run the test suit:

    python setup.py test

Though I could not reproduce this, one user reported having to set an environment variable to install:

    export CFLAGS="-I /usr/local/lib/python3.6/site-packages/numpy/core/include"
