r2n - get perpendicular components of a vector

r2n rname x y z

r2n reads an lc catalog containing positions rname[3] from stdin, evolves the positions and outputs a two-vector n[2] which are the components of the unit vector |rname| perpendicular to the direction (x, y, z).  The reference vector (x, y, z) need not be normalized.
