class TPointsArray3D: public TPoints3DABC


 TPointsArray3D is an abstract class of the array of 3-dimensional points.
 It has 4 different constructors.

 This class has no implementation for Paint, Draw, and SavePrimitive methods

   First one, without any parameters TPointsArray3D(), we call 'default
 constructor' and it's used in a case that just an initialisation is
 needed (i.e. pointer declaration).

       Example:
                 TPointsArray3D *pl1 = new TPointsArray3D;


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

       Example:
                 TPointsArray3D pl1(150);


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

       Example:
                 TPointsArray3D 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:
                 TPointsArray3D pl1(150, xArray, yArray, zArray);
