!!!Almost all the the Swarm-Sim core libaries written at the HHU has no code smells!!!!! :)))) Only vis.py has code smells and this is not written by HHU. And multiple.py as well and some solutions. But in total all the core libaries/interfaces of the Swarm-Sim has no code smells. Yeapy!!!! Changes: The scanning for matters method has been modified and refactored. The header became a new function called scanning. The stl_lib for the scenarios became to methods. One for creating particles in hexagon. The other one for creating a hexagon border with tiles.
