Iteration 1

* Simple, starting point
* Function: 
    scribble, no store/no save 
* Try: resize, cover it with another window, minimize/restore. 

  package scribble1
    scribble1/Scribble.java
    scribble1/ScribbleCanvas.java
    scribble1/ScribbleCanvasListener.java


Iteration 2

* Add basic functions 
* Enhancement by modification 
* Functions:  
    scribble, stored 
    menu bar
    color selection: color chooser   
    file handling: new, open, save, save as, save on exit 
    file chooser: open, save as, 
    dialog: about, exit

    scribble2/ScribbleCanvas.java	
    scribble2/ScribbleCanvasListener.java
    scribble2/Stroke.java
    scribble2/ColorDialog.java


Iteration 3

* Refactoring 
* Builde an extensible architecture 
* Desired extensions 
  Drawing functions:
    scribble, line, oval, rect, eraser 
* Template methods to allow refinement of ScribbleCanvas and ScribbleCanvasListener
* Shape - Stroke 
* Tool - AbstractTool - ScribbleTool

Iteration 4

* Enhancement by extension 
* Function 
    drawing tools: scribble, line, oval, rect, eraser 
* Have a few basic features working in the architecture 
* Toolkit, interaction: toolbar -> toolkit -> canvas -> listener 
* TwoEndsShape, line, oval, rect
* TwoEndsTool
