33    @brief Asteroid field with lots of parameters. Derived from asteroidField.lua
34
35    Generates a bunch of asteroids that may contain some stuff.
36    It is required to wait until all XML-arguments are set. That's why the actual
37    generation happens when tick() gets called for the first time.
