 Conversion of geocentric coordinates to LatitudeLongitude coordinates (Site not responding. Last check: 20070917) 
  The values are stored in the variables pointed to by lat and lon, the height above the ellipsoid in meters is stored in h. 
  intCC_geo2lld(double a, double e2, double x, double y, double z, double *lat, double *lon, double *h)convert geocentric to latitudelongitude (degree)This function converts the geocentric coordinates in x, y and z to the geographic latitude and longitude (in seconds degree) pointed to by lat and lon. 
  It returns 1 if the calculation could be solved with 500 iterations or 0 if the iteration could not be solved with the maximum number of iterations.
