Description: Creates realistic random trajectories in a 3-D space
        between two given fix points, so-called conditional empirical
        random walks (CERWs). The trajectory generation is based on
        empirical distribution functions extracted from observed
        trajectories (training data) and thus reflects the geometrical
        movement characteristics of the mover. A digital elevation
        model (DEM), representing the Earth's surface, and a background
        layer of probabilities (e.g. food sources, uplift potential,
        waterbodies, etc.) can be used to influence the trajectories.
