Algolab 2021

My code for the problems given in the ETH course Algorithms Lab in Fall 2021. Problems descriptions and testcases not included. I did not put as much effort into this as this guy did, but I took some inspiration :) Also credits to the creators of the algolabVS.sh with which this stuff was done (+ Code Expert).

Code requires C++, CGAL, BGL. See https://cadmo.ethz.ch/education/lectures/HS21/algolab/technical.html.

E.g. on Ubuntu, run

sudo apt-get install build-essential libboost-all-dev libcgal-dev cmake cmake-data
