    This while loop is repeating a block of code which checks the security of user's password.
    The loop continues while character, digit, punctuation mark or upper case character number is not
    satisfactory (any variable == "missing").
    The while loop:
    - uses if statement inside for loop to count number of different types of characters in the password
    - uses if statements to check if there is enough of different types of characters
    - assigns the "missing" or "good" value to check_variables
    - prints password healthcheck report with safety tips for the user
    - asks user for another password changed accordingly to given feedback
    The while loop terminates when user's password is safe and all check_variables == "good".
