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!

!!!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.

sim.py renamed to world.py
run.py renamed to swarm-sim.py
swarm-sim.py got a new structure for initializing the swarm-sim and calling the solution. The solution calling is independent from vis.py
vis.py: The run method is renamed to draw_world. Solution is not called anymore inside of this method. A new variable called refresh_time is added. The draw window is getting refreshed after each solution has been called and refresh_time is over.

header.py: in the lib a header.py is inserted. In this file all the standards color and direcotries are defined. As well some standard methods for checking or changing the directions.

And fixed a small bug in particle.py

And caps the Marker in sim.py

Bugfix run.py and config.py
