Created "simulator/utils/topography/TopographyHelper.java" to encapsulate common methods for cognition and locomotion layer which rely on the topography

In "CounterflowCognitionModel.java", imitate "SelfCategory.EVADE" if neighbor is also "SelfCategory.EVADE"

use the default values of AttributesFloorField for generating a distance function if there is no attribute defined in the json file, i.e. a grid resolution of 0.1.

Implemented first version of "CounterflowCognitionModel.java" and corresponding unit test (but behavior on locomotion layer is missing)
