/**
 * Sub package of the Dynamics package containing joints.
 * <p>
 * Joints are connections between bodies that limit their relative motion.  
 * <p>
 * Joints are solved using an iterative constraint based approach in the same manner as contacts.
 * <p>
 * All joints, with exception of the {@link org.dyn4j.dynamics.joint.PinJoint} join a pair
 * of {@link org.dyn4j.dynamics.PhysicsBody}s.
 * <p>
 * Current joint implementations:
 * <ul>
 * <li>{@link org.dyn4j.dynamics.joint.AngleJoint} for constraining the rotation of two bodies</li>
 * <li>{@link org.dyn4j.dynamics.joint.DistanceJoint} for fixed length distance, spring/damper, and limits</li>
 * <li>{@link org.dyn4j.dynamics.joint.FrictionJoint} for applying friction, air resistance, joint
 * friction, etc</li>
 * <li>{@link org.dyn4j.dynamics.joint.MotorJoint} primarily for character control</li>
 * <li>{@link org.dyn4j.dynamics.joint.PinJoint} specifically to connect a distance joint with
 * spring/damper to one body</li>
 * <li>{@link org.dyn4j.dynamics.joint.PrismaticJoint} for only allowing relative linear motion
 * along an axis with or without a motor and limits</li>
 * <li>{@link org.dyn4j.dynamics.joint.PulleyJoint} for creating a pulley with or without block-and-
 * tackle</li>
 * <li>{@link org.dyn4j.dynamics.joint.RevoluteJoint} for only allowing relative rotation with or
 * without a motor</li>
 * <li>{@link org.dyn4j.dynamics.joint.WeldJoint} for connecting two bodies together completely</li>
 * <li>{@link org.dyn4j.dynamics.joint.WheelJoint} for connecting two bodies in a frame-wheel type
 * configuration with linear spring/damper and angular motor</li>
 * </ul>
