/**
 * The aplication is separated in seven classes.We have the MaFrame class to start
 * the program.These class extends JFrame class,just initialize the different classes(Dessin,North and South),
 * and place components of these classes on the good position.
 * 		Arc and Node classes are just classes respectively using Kruskal Class.This class is used to run Kruskal Algorithm.
 * The three main classes for general design of aplication are Dessin,North and South classes.
 * 		The Dessin class extends JPanel class.This class can disply all the design of vertices and arcs with graphics2D.
 * This Graphics2D class extends the Graphics class to provide more sophisticated control over geometry,coordinate transformations,
 * color management, and text layout.This is the fundamental class for rendering 2D shapes,text and images on the Java platform.
 * 		North and South classes must have an object Dessin to run, because it is with these classes that user will be say to the
 * aplication what he wants to do, and after the user say waht he want, the diplay must be refreshed.
