• It is mandatory to set the root url and appId:

      myApp.config(['zlAuthProvider', function(zlAuthProvider){
          zlAuthProvider.setAppId(appId)
              .setRootUrl(authUrl)
      }]);

You can also set loginRoute (defaults to /user/login) and token refreshRoute (/user/refresh)

• If a token is found in location.hash (the user has been redirected from login page) or in local storage, the module will use it.
• Set zlAuth.getToken() as your token provider whenever you need id. This returns a promise that will be resolved immediately if the token is still valid, or after refreshing it. If there is no way to obtain a valid token, the module will redirect the user to loginRoute.
