+ * @brief Describe the contact point between two geoms.

+ * If two bodies touch, or if a body touches a static feature in its 
+ * environment, the contact is represented by one or more "contact 
+ * points", described by dContactGeom.
+ *
+ * The convention is that if body 1 is moved along the normal vector by 
+ * a distance depth (or equivalently if body 2 is moved the same distance 
+ * in the opposite direction) then the contact depth will be reduced to 
+ * zero. This means that the normal vector points "in" to body 1.
