Bonus: Develop a GUI to setup simulation
Currently, the user is confronted with the simulation screen right away.
Please extend the visualization by a GUI such that:
- the user can set up a new simulation with arbitrarily many vehicles (and vehicle types)
- the user can see available maps
- the user can see available simulations (and use them as a template for new simulations)
- the user can download the created simulation as a sim file
- the user can see and replay available simulations
Note: some of the functionality is not provided by the back end yet which is OK.
