"""
In SuperCigarette company questionaries are collected everyday by hostesses.
By end of each day secretary inserts values into system.
Each record is name, email and age of a user.

// change age to birthdate, to be precise

There is a need to automate:
        - creating unique usernames (just for the list provided below, no database of course!)
        - creating dedicated string message for under age user
        - validate email
        - validate age
        - prepare dedicated message for under age user
        - proper exceptions handling is nice thing to have
Our programmer had time just to do some of the work.
Please finish what he started so main() function gives us what is described above
