UDM Group Matrix

Generates a user-group matrix from an Univention Directory Manager export

1. Create a UDM dump using univention-directory-manager users/user list > userdump.txt
2. Run pipenv install and pipenv shell.
3. Run main.py. It outputs CSV-data to stdout that you can redirect to disk and open with your favorite spreadsheet tool. It also generates a graphical representation using matplotlib and saves that to matrix.png.
