/**
 * 

The {@code CubiCurve} class defines a cubic Bézier parametric curve segment * in (x,y) coordinate space. Drawing a curve that intersects both the specified * coordinates {@code (startX, startY)} and {@code (endX, enfY)}, using the * specified points {@code (controlX1, controlY1)} and {@code (controlX2, controlY2)} * as Bézier control points. * Example:

*
import javafx.scene.shape.*;

CubicCurve cubic = new CubicCurve();
cubic.setStartX(0.0f);
cubic.setStartY(50.0f);
cubic.setControlX1(25.0f);
cubic.setControlY1(0.0f);
cubic.setControlX2(75.0f);
cubic.setControlY2(100.0f);
cubic.setEndX(100.0f);
cubic.setEndY(50.0f);
