Wrapping up the code in a Python package

[krzdur]

Hello, Klaudia,
Thank you for the work you've done to simplify the IV and WOE analysis. For convenience, I've created a Python package using your code so it's even easier to work with it. Feel free to merge it to your repo (perhaps in a separate branch) and publish it in PyPI - you take all the credit.

What I changed:

• moved AttributeRelevance.py and Features.py into a separate directory that serves as a source for package builder;
• added setup.cfg and pyproject.toml with instructions for package builder. I put your name into the author field
• added an MIT license file - feel free to change it to any other you find suitable
• moved Jupyter notebooks with usage examples into examples directory
• added requirements.txt and made some minor adjustments in .gitignore

I did not change anything in your code in AttributeRelevance.py and Features.py.
