Each car, station with pump, and queue consumer work in their own threads. There is a timer that syncs them.
The purpose of simulation is to find an optimal station/pump/queueing setup. The metric is an avarage waiting time of a car.
Future ideas: more stations, more pumps, transactions, visualising, online game etc.
Have fun!

- Is getting hard to read
- Out of date
- All need refactoring but now work on a right basis
- The code is completely WIP
- Report in unstructured and needs its own object
- Report shows in runner before the last car gets finished
- Report needs aggregations
