Refactored "osm2vadere.py" and added unit test "test_osm2vadere.py" (written by Maximilian Niedermaier).

fix a problem with the AreaSoeedProcessorTest and PedestrianVelocityProcessorTest: Wrong expected values.

Bugfix in "Simulation.java": "cognitionLayer.prioritizeEventsForPedestrians()" must be called after "sourceController.udpate()" and "topographyController.update()".

Note: Long lines cause warnings in some text editors.

A new issue was created to find the core problem or to implement a
re-translation of the origin only for simulation time

fix wrong polygon intersection computation, add an additional PedestrianFundamentalDiagramProcessor.

quick fix in PedestrianVelocityProcessor: the velocity was NaN if the duration was 0.0 now the velocity will be 0.0

Dev/step size adjuster
