Password Strength Factors and Weightings

password length:
level 0 (0 points):  less than 7 characters
level 1 (3 points):  between 7 and 10 characters

letters:
level 0 (0 points): no letters
level 1 (5 points): all letters are lower case
level 2 (7 points): letters are mixed case

numbers:
level 0 (0 points): no numbers exist
level 1 (5 points): one number exists

combinatons:
level 0 (1 points): letters and numbers exist
level 1 (1 points): mixed case letters
level 1 (2 points): letters, numbers 
level 1 (2 points): mixed case letters and numbers exist
