  Surface Area and Volume of Geometrical Objects

    \item \code{g.sphere} the surface and volume of a sphere
    \item \code{g.spheroid} the surface and volume of a spheroid
    \item \code{g.cylinder} the surface and volume of a cylinder;
      note that the surface area calculation ignores the top and bottom.


g.spheroid (x, b=1)
g.cylinder (x, L=1)


  \item{x }{the radius 
  \item{b }{the ratio of long/short radius of the spheroid;
    if b<1: the spheroid is oblate.
  \item{L }{the length of the cylinder

  A list containing:
  \item{surf }{the surface area 
  \item{vol }{the volume
