GinJWTMiddleware provides a Json-Web-Token authentication implementation. On failure, a 401 HTTP response is returned. On success, the wrapped middleware is called, and the userID is made available as c.Get("userID").(string). Users can get a token by posting a json request to LoginHandler. The token then needs to be passed in the Authentication header. Example: Authorization:Bearer XXX_TOKEN_XXX
