Added two new output processors ("PedestrianMostImportantEventProcessor" and "PedestrianEventProcessor") and use them in "TrajectoryReader".

In "OSMBehaviorController.swapPedestrians()", improved bug fix to avoid "AssertionError" in "VTrajectory".

We have to do a code review here with Bene if event-driven update scheme is used properly.

In "OSMBehaviorController.swapPedestrians()", fixed bug ("pedestrian1.setTimeOfNextStep()" was not called).

Added print statements in "OSMBehaviorController" to debug why salient behavior causes an "AssertionError" when using event-driven update scheme.

In "DefaultModeAdapter", made resizing of scenario elements a two-step process: first, select element, then use resize handles at object edges.

Since commit c91dad12, a scenario element was selected when hovering over it.
This caused problems in the postvisualization. It was very tricky to track one
specific agent because when you moved the mouse cursor over the canvas different
agents were selected immediately. Therefore, I have reverted this behavior and
resizing a scenario is a two-step process now.

Added test scenarios for salient behavior: "03-UnidirectionalFlow-OSMSequential.scenario" and "04-CounterFlow-OSMSequential.scenario".

Added "angleCalculationType" and "targetOrientationAngleThreshold" to "AttributesAgent" and use it in "OSMBehaviorController".

Handle salient behavior in "UpdateSchemeSequential" and reduced "requiredFootSteps" from "5" to "2" in "SalientBehaviorCognition".

Make shapes resizable

See merge request !56

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".

Measurement area refactor processors rebased

See merge request !55

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".
