A minimum python project setting to support for src layout without considering distribution.

pyproject.toml

# Add this file into the root folder of your project
# Specify dependencies in requirements.txt and install dependencies with `pip install -e .`
# Then, you don't need to specify the `src` directory within PYTHONPATH when you run a python module in your project.
# This is an exeperimental/opinionated setting. So any comments are welcome.
