Why is Authenticator func a required?

[dhdresser]

Thanks for creating this great jwt middleware. Authenticator func is only called by LoginHandler(). If I want to write MyOwnLoginhandler() where I create my own claims and signing, I wouldn't need to set Authenticator then, but it is requirement set in the MiddlewareInit(). Right now I set Authenticator to return "", true.

Question... Would moving the check for Authenticator == nil in MiddlewareInit() to the LoginHandler() function be better suited? or maybe making this field optional? That way its not a hard requirement for those who wouldn't use LoginHandler.
