Class Description

 PolyMarker3D is a 3D polymarker. It has three constructors.

   First one, without any parameters TPolyMarker3D(), we call 'default
 constructor' and it's used in a case that just an initialisation is
 needed (i.e. pointer declaration).

       Example:
                 TPolyMarker3D *pm = new TPolyMarker3D;


   Second one, takes, usually, two parameters, n (number of points) and
 marker (marker style). Third parameter is optional.

       Example:
                 TPolyMarker3D (150, 1);


   Third one takes, usually, three parameters, n (number of points), *p
 (pointer to an array of 3D points), and marker (marker style). Fourth
 parameter is optional.

       Example:
                 Float_t *ptr = new Float_t [150*3];
                         ... ... ...
                         ... ... ...
                         ... ... ...

                 TPolyMarker3D (150, ptr, 1);
