From: Marcel Graf <marcel_graf.1@outlook.de>
Date: Fri, 21 Nov 2025 21:01:43 +0100
Subject: [PATCH] Created Dockerfile that sets up a container on which the
 requested tasks can be run. Created yaml.sh for setting up the desired
 yaml-cpp installation while the container is built. Created a CMakeLists.txt.
 Adapted build_and_run.sh.
