loadingType [LoadingType]:
indicate that the dynamic potential field should calculate a individual loading for each pedestrian or uses a constant loading strategy. This will be done by the loading strategies. If the loadingType=CONSTANT_RESPECT_TARGETS than pedestrianSameTargetDensityWeight and pedestrianOtherTargetDensityWeight has to be set. If loadingType=CONSTANT than pedestrianWeight has to be set.
