detection proceeds from the center outwards.
Double: similar to Fast, except that both circles are moved
in case of a collision.
Random: similar to Fast, except that collision detection is
randomized rather than sorted.
Simple: similar to Fast, but without a contraction pass
after every collision iteration.";
