Programming Challenge: 12 - Password Verifier

Six characters? Seriously? Set the minimum password length to twelve characters.

We will also require that the password not contain any space characters.

In addition to the requirement that the password contain at least one upper case letter and one lower case letter, add the additional requirement that the password contain at least one special character. We will assume that any character that is printable, not alphabetic, not numeric, and not a space character is "special." That includes punctuation, but may include additional non-punctuation characters.

Write functions to complete these tasks as appropriate.
