"""Character Sets

Defines strings of characters and an exclude function that can be used either as
the alphabets for you character-base passwords or as building blocks used to
construct a new alphabet for you passwords.

To create an alphabet with all characters except tabs use either:
    'alphabet': exclude(PRINTABLE, '\t')
    'alphabet': ALPHANUMERIC + PUNCTUATION + ' '

# Exclude function
