normalize() method

$nEmail = new MioVisman\NormEmail\NormEmail();

$email = $nEmail->normalize($email);

• Method does not validate email address

• Do not use normalized email to send emails

• Use a normalized email to check the ban or uniqueness of the email of a new user. Check on the normalized emails ;)
• The domain is lowercase (and in Punycode)
• The local part is lowercase unless otherwise specified
• The local part after the "+" is truncated (for Yahoo domains - after the "-")
