//______________________________________________________________________________
// TPoints3D is an abstract class of the array of 3-dimensional points.
// It has 4 different constructors.
//
// This class has no implemenatation for Paint, Draw, and SavePrimitive methods
//
// First one, without any parameters TPoints3D(), we call 'default
// constructor' and it's used in a case that just an initialisation is
// needed (i.e. pointer declaration).
//
// Example:
// TPoints3D *pl1 = new TPoints3D;
//
//
// Second one is 'normal constructor' with, usually, one parameter
// n (number of points), and it just allocates a space for the points.
//
// Example:
// TPoints3D pl1(150);
//
//
// Third one allocates a space for the points, and also makes
// initialisation from the given array.
//
// Example:
// TPoints3D 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:
// TPoints3D pl1(150, xArray, yArray, zArray);
//
