+// In case you want to construct G4EllipticalCone from :
+//   1. halflength in Z = zTopCut
+//   2. Dx and Dy =  halflength of ellipse axis  at  z = -zTopCut
+//   3. dx and dy =  halflength of ellipse axis  at  z =  zTopCut 
+//      ! Attention :  dx/dy=Dx/Dy 
+//
+// You need to find xSemiAxis,ySemiAxis and zheight:
+//
+//  xSemiAxis = (Dx-dx)/(2*zTopCut)  
+//  ySemiAxis = (Dy-dy)/(2*zTopCut)
+//    zheight = (Dx+dx)/(2*xSemiAxis)
