+The first exercise is based on fourth lecture about linear transformation.
 In this exercise we will implement the transformation of simple geometrical shapes. So far we can instantiate shapes in the main method (view/swing/Main.java) like the 2DLine. Notice that this object is put into the shapeList of type PaintableShape. However, while running the application we can only see parts of the line in the top left corner.
