  Maintenance log started on November 16th, 2000 by Laurentiu Cristofor

  Nov. 16th, 2000   - made some style changes
                    - changed a label from "Algorithms Selected" to
                      "Selected Algorithms"

  Nov. 17th, 2000   - changed the text for more labels/error messages
                    - renamed some methods
                    - introduced dialogs for errors instead of 
                      System.out calls

  Nov. 21st, 2000   - resized and repositioned widgets
                    - added button shortcuts
