2D Intersection - Ray-Circle

[npruehs]

Implement a ray-circle intersection test with the following signature:

public static bool Intersects(this Ray2F ray, CircleF circle)

Call that method from

public static bool Intersects(this CircleF circle, Ray2F ray)

If you can, provide an overload with an out parameter containing the intersection point(s).

Write at least one unit test illustrating your solution, and/or add any reference links as comments.
