// This file implements a basic menu management library in the Arduino SDK
//
// @brief
// This is a menu management library. The library allows user to create
// an intire menu tree with relatively few lines of code.
// The library allows the users to define callbacks able to overload internal
// functions (i.e. navigation device management) or to be executed inside a menu.
// It is possible to define also splash screens and a default user screen to be
// activated after a time interval since the last interaction
//
