vec_t plane_s::dist

distance from the origin to the plane. unit normal and distance description is http://mathworld.wolfram.com/HessianNormalForm.html though the sign of the distance seems to differ from the standard definition. (or the direction of the normal differs, the effect is the same when calculating the distance of a point from the plane.)
