about Password Scheme

[yt8492]

Password Scheme ALPHA_NUMERIC_SYMBOLS and ALPHA_NUMERIC_MIXED_CASE_SYMBOLS can't recognize "_" as symbol. This is my suggestion in android-saripaar/saripaar/src/main/java/com/mobsandgeeks/saripaar/rule/PasswordRule.java
put(Password.Scheme.ALPHA_NUMERIC_SYMBOLS, "(?=.*[a-zA-Z])(?=.*[\\d])(?=.*([^\\w]|_)).+"); put(Password.Scheme.ALPHA_NUMERIC_MIXED_CASE_SYMBOLS, "(?=.*[a-z])(?=.*[A-Z])(?=.*[\\d])(?=.*([^\\w]|_)).+");
