  Color StaticColor[]; // Color matrix array (static).
  Color UserColor[];   // Array of colors that user has created (not static).
  Color RBColor[];     // Array of colors (one color for each Radio Button).  
  int CurRButton;      // Index of the currently selected radio button.
  int userIndex;       // Index in UserColor array to put the next color
                       //  the user wants saved.

  Color curc;          // Currently selected color.
  int r, g, b;         // Red, green, and blue values of the current color.



  // The UserColor array works just like the StaticColor array except that the 
  // user can change the colors in the UserColor array.  Therefore, when 
  // different color boxes are clicked in either array, curc, the color for 
  // the currently selected radio button, the scrollbars and the textfields all
  // change to show the same current color.  When curc in the model is changed,
  // by using one of the controllers, the view is changed as follows:  the color
  // used for the currently selected radio button changes, as do the scroll bars
  // and textboxes. At all times, the scroll bars, the curc variable in the 
  // ColorFrame class, the currently selected radio button and the textfields
  // display the same color.  When the RBColor array changes, the view will also
  // change to show the new color for the radio button that was updated.  When 
  // CurRButton in the model changes, this changes which index colors will be 
  // stored in the RBColor array. Also, when CurRButton changes, the curc in 
  // ColorFrame current changes to reflect the color of the currently
  // selected radio button.
