+@enumerate
+@item Accepts user data to be added to the dictionaries that are tested
+against (name, birthdate, etc.)
+@item Gives a score to the password, from 0 (terrible) to 4 (great).
+@item Provides feedback on the password and ways to improve it.
+@item Returns time estimates on how long it would take to guess the password
+in different situations.
