bug-fix-1

[chiertu]

1. requirements.txt — there were multiple imports of ortools~=9.7, I edited to keep only 1
2. Dockerfile — for me, it was necessary to add “RUN apt install -y gdal-bin libgdal-dev”, otherwise docker build errors out when installing gdal dependency for fiona, which in turn is a dependency for geopandas. It takes significantly longer to build.
3. README.md — add usage instructions, clean up the contact info
4. GenerateDistMatrix.py — clean up the config statements
5. config_mapbox.ini is moved out of /code and into /util

Will continue to fix bugs and improve documentation
