Example usage: 

 String password = new PasswordGenerator()
    .lower().count(3)  // Exactly three lower case characters
    .upper().count(2)  // Exactly 2 upper case characters 
    .numbers().min(5).exclude("012345".toCharArray()) // At least five numbers, from 6 to 9.
    .symbols().min(6).max(10) // Between 6 and 10 special characters
