33    @brief Asteroid belt with lots of parameters. Derived from asteroidField.lua
34
35    Generates a ring of asteroids by calling SpicedAsteroidField multiple times.
36    It's in the xy-plane at default, orientation can be changed with tiltAt
37    (angle where it gets elevated/lowered the most) and TiltBy (angle at z-axis).
38    This doesn't work very well and could probably implemented differently with
39    relative coordinates (attach etc, stuff in WorldEntity).
40
41    It is required to wait until all XML-arguments are set. That's why the actual
42    generation happens when tick() gets called for the first time.
