Creates a list consisting of the three dimensional probability distribution cube for turning angle, lift angle and step length (turnLiftStepHist) as well as the uni-dimensional distributions of the differences of the turn angles, lift angles and step lengths with a lag of 1 to maintain minimal level of autocorrelation in each of the terms. Additionally also the distribution of the flight height over the ellipsoid (absolute) and the distribution of flight height over the topography (relative) can be included.
