* The code is a mess for now. I'm not sure if there is any reason to
send a whole event to UI, it's better to send InterfaceWithData.
* Sending to queue from Menu isn't great as well.
*Menu class now is responsible for the whole logic with
temperature and set_point.
*void NotifyAndRefreshUI (const char *str) is a placeholder
for sending a string value on a queue to UI task,
which will handle the lcd screen.
*Added error return value to Manager::parseEvent(Event* e)
