1. The best, but unsafe __init__.py I made

Una volta usato il seguente file init.py è possibile chiamare le funzioni nella stessa cartella che hanno nome file e funzione con lo stesso nome, basta solo chiamare il package.

Nota: Il file init.py non deve essere mai più modificato (bene e male perchè fa tutto in atomatico, ma contiene un exec alla fine del codice)
