36 // Class description:
37 //
38 // Defines the EventAction used during tracing of magnetic field
39 // lines. During the EndOfEventAction() it stores magneticfield lines
40 // as polyline and polymarker objects.
41 // These polyline and polymarker objects can be drawn by using the
42 // DrawFieldLines() method.
