Detailed Description

Class Navigator does the Navigation in the menu and updates the display.

Interaction from outside is done by calling moveUp(), moveDown() or select(). Could be done by an RPG or via Buttons.

Example:

 #include "MenuItem.h"
 #include "Menu.h"
 #include "Navigator.h"
 #include <vector>
 #include <string>
 PinDetect  T1 ( p21,PullNone); //Button 1 - UP
 PinDetect  T2 ( p22,PullNone); //Button 2 - Down
 PinDetect  T3 ( p23,PullNone); //Button 3 - Select
 ...
     // Here is the heart of the system: the navigator. 
     // The navigator takes in a reference to the root and a reference to an lcd
     Navigator navigator(&rootMenu, &lcd);
     
     // attach the methods for buttons Up, Down, Select to the navigator
     T1.attach_asserted( &navigator, &Navigator::moveUp);
     T2.attach_asserted( &navigator, &Navigator::moveDown);
     T3.attach_asserted( &navigator, &Navigator::select);
     // do whatever you need to do in your main-loop.
        while( 1 ) {
          led4 = !led4;
          wait( 1 );
        }
