    These functions are used to validate a user's password, that is, are they entering a password that
    meets the minimum password requirements. This is used in real time, it is call on the KeyUp event
    as the user is entering their new password and when changing their password.
    
    There are also functions used in conjunction with choosing a username that indicate, in real time,
    if the string they have entered is available as a username.

    // Finding special characters was challenging.
    // I found it works best to seperate the otherwise long list of choices.
    // When the last 2 regex's were put together, at least in certain combination,
    //  it was matching any digit. I never figured this out but splitting them seems to somehow fix it.
