- Added new scenario element `TargetChanger`. This scenario element has an arbitrary shape and changes the target of an agent. Either to another static target or to another agent (to get a follower behavior). A `TargetChanger` has two important parameters:
*`changeTargetProbability`: This defines how many percent of the agents, who enter the area, should change their target.
*`nextTargetIsPedestrian`: If `nextTargetIsPedestrian == false`, assign a new static target. Otherwise, randomly choose a pedestrian (with given target id) to follow.
### Changed
-`FootStepProcessor` interpolates the pedestrian's foot step to obtain a more precise position.
Was previously known as `PedestrianFootStepProcessor`
