Function duckduckgeo::gravitate

pub fn gravitate<T: GravityTrait, K: GravityTrait<N = T::N>>(
    a: &mut T, 
    b: &mut K, 
    min: T::N, 
    gravity_const: T::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.
