Implemented first (rudimentary) working version of "SalientBehavior.COOPERATIVE" in "OSMBehaviorController" and "UpdateSchemeEventDriven" (but visualization seems to be broken).

In "OSMBehaviorController", added TODO and commented out code to avoid "AssertionError" in LinkedCellGrid.

Started to implement method "swapWithClosestCooperativePedestrian()" in class "OSMBehaviorController".

VadereUtils/src/org/vadere/util/geometry/shapes/IPoint.java:
- Implemented default method "dotProduct()" including unit tests in "IPointTest.java".

Started to implement method "swapWithClosestCooperativePedestrian()" in class "OSMBehaviorController".

VadereState/src/org/vadere/state/scenario/Pedestrian.java:
- Fixed bug in copy constructor: member "salientBehavior" was not copied.

Renamed "CognitionLayer" to "EventCognition", added class "SalientBehaviorCognition" and added test scenario "01-ExperimentSetup.scenario".
