Thanx to Gorden Wunderlich

Changed the color attribute name vilolett to violet because of spelling misstake. German to English.

methods of particle.py

The direction enum/list has been renamed to direction_list.

All the contents of str_lib of solution and scenario and the header in lib are moved to one file called swarm_sim_header.py

Some bugs has been fixed!

In  scenario std_lib the method add_tiles_as_hexagon got a new
attribute color for setting the color of the tiles.

!!!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.

The random seed is moved from world.py to swarm-sim.py, because the simulator is responsible for the randomness.

memory_limitation

- For the reading the data of the config the classe ConfigData is created
in a seperated file called config.py

- For the visualization a bug is fixed. The bug was that whenever
the vis.py goes into a sleep it is not possible to zoom or to create
tiles. !This bus has been fixed by Karol Actun!

- Three methods sim_to_coords, coords_to_sim, check_coords are moved
from the world.py to the header.py. Because those methods are
independent from the world.py. Based on these change some changes
have to been made on the other files.

- The particle counter has been removed from particle.py. The counting
of the particle and given the particle a number based on the counting
is happening now in world.py.

- Some unnecessary variables have been deleted from the matters.
