Program: MKFASTSPH2CART

  mkfastsph2cart......spherical to cartesian transformation
 
  call: [x,y,z]=mkfastsph2cart(az,elev);
 
                az: azimuth angle (= longitude) [radian]
              elev: elevation angle (=latitude) [radian]
 
  result: x,y,z: the corresponding cartesian coordinates
 
  This is an abridged version of matlab's sph2cart version. It does not use
  the radius coordinate, since this is in many cases not important. It also
  tries to reduce the number of operations.
 
  This seems to be about 30% faster than the original, but is invalid if
  the radius coordinate is relevant for you.
