Classpublic class Contact

Depicts pairwise contact information

To resolve collisions, the CollisionResolver needs to know both bodies involved, the point of contact in world coordinates, and the collision normal (points outward from incident edge).

TODO: This needs to eventually be generalized to allow for particles
