INPUT FORMAT for the first assignment:

The input file should be given as a command line argument. 
1. First line of the file : Number of vertices 
2. Rest of the lines of the file: x y coordinates of the
   vertices of the polygon, in clockwise order; 
   (if you have started with counter clockwise order, that is also fine)
   One vertex coordinates per line.
3. Your output should be a visual representation of the original 
   Polygon and the triangulation. 
   (Please output the n-2 triangles if visualisation is not implemented.
   The assignment would be graded accordingly!)
