// The applet has three main parts:

//     the ControlPanel, with control buttons and a step counter, and
//     the Board, which is where the ant runs around.

        // Then specify their layout within ("add" them to) the applet.

        // internal layout.
        // Then "this.validate()" forces actual calculation of
        // everybody's layout, including their bounds(), based on the
        // height=... and width=... in the <applet...> tag.
        // Then init the board, which needs to know its bounds() to
        // set its array size.
        
        // After the Board b and ControlPanel c are created,
        // we pass b to c.init().  c passes itself to b.init(),
