PedestrianMaxDegreeOfExposureProcessor

Log the degree of exposure when a pedestrian reaches its final target. If a pedestrian does not reach the target before the simulation ends, log current degree of exposure (i.e., we enter the post loop and the topography still holds pedestrians). Use a simple map with pedestrian.getId() as key and update the value in each simulation step. This is a naive and inefficient approach, but it works.
