 *  Menus
 *  The Radio menus are accessed by tapping on the function button. 
 *  - The main loop() constantly looks for a button press and calls doMenu() when it detects
 *  a function button press. 
 *  - As the encoder is rotated, at every 10th pulse, the next or the previous menu
 *  item is displayed. Each menu item is controlled by it's own function.
 *  - Eache menu function may be called to display itself
 *  - Each of these menu routines is called with a button parameter. 
 *  - The btn flag denotes if the menu itme was clicked on or not.
 *  - If the menu item is clicked on, then it is selected,
 *  - If the menu item is NOT clicked on, then the menu's prompt is to be displayed
