// The basic menu code
// If you add an app, this is where you will update the
// framework code to include it in the menu.
//
// Make the following updates:
// 1) Update maxApp to the total number of apps.
// 2) Update appName to add the title of the app.
// 3) in the main routine in GrumpyWatch, add a case to the switch statement to call your app routine.
