Class Description

 PolyLine3D is a 3-dimensional polyline. It has 4 different constructors.

   First one, without any parameters TPolyLine3D(), we call 'default
 constructor' and it's used in a case that just an initialisation is
 needed (i.e. pointer declaration).

       Example:
                 TPolyLine3D *pl1 = new TPolyLine3D;


   Second one is 'normal constructor' with, usually, one parameter
 n (number of points), and it just allocates a space for the points.

       Example:
                 TPolyLine3D pl1(150);


   Third one allocates a space for the points, and also makes
 initialisation from the given array.

       Example:
                 TPolyLine3D pl1(150, pointerToAnArray);


   Fourth one is, almost, similar to the constructor above, except
 initialisation is provided with three independent arrays (array of
 x coordinates, y coordinates and z coordinates).

       Example:
                 TPolyLine3D pl1(150, xArray, yArray, zArray);
