PROJPOINTONCIRCLE3D Project a 3D point onto a 3D circle.

   PT2 = projPointOnCircle3d(PT, CIRCLE).
   Computes the projection of 3D point PT onto the 3D circle CIRCLE. 
   
   Point PT is a N-by-3 array, and CIRCLE is a 1-by-7 array.
   Result PT2 is a N-by-3 array, containing coordinates of projections of
   PT onto the circle CIRCLE.
