/**  A SpacePoint in cylindrical coordinates.

     A cylindrical coordinate is specified by a radius $r$ (distance
     from the origin), an angle $\phi$ and a position along the $z$
     axis.  The angle $\phi$ is measured in the $(x,y)$ plane, with
     $\phi = 0$ being the $x$ axis, and $\phi = \pi/2$ the $y$ axis.
