Function duckduckgeo::gravitate

pub fn gravitate<N: Float + MyNum>(
    bots: [(Vec2<N>, N, &mut Vec2<N>); 2], 
    min: N, 
    gravity_const: N
) -> Result<(), ErrTooClose>

Returns the force to be exerted to the first object. The force to the second object can be retrieved simply by negating the first.
