 * Generates a sphere around the y-axis centered at the origin including

 *     num_rings    Number of full rings not including the top and bottom 
 *    caps. 
 *     num_sections Number of sections each ring is divided into.  Each

 *    perfect sphere.

 *     pnum_v       On exit contains the number of vertices. 
 *     pnum_tri     On exit contains the number of triangles.
