 The application consists in three different execution flows.
 
 The main thread waits for eventual [user actions](#user-interactions-during-application-execution) (by putting the terminal in raw mode through the ```crossterm::screen::raw::into_raw_mode()``` function and creating a ```crossterm::SyncReader``` which allows to read the input synchronously); in doing so it signals to the secondary threads when to pause or resume their work.
