Identify user

MarkTag automatically assigns an unique ID to every user. But you can add more information to farther classify the user.

Marktag.instance.SetUser("test@test.com", "1234567890");

Note that if you call Marktag.LogLogin() or Marktag.LogSignup() upon authentication, you can skip this step. But you can still use this when you expect the user to be already logged in to your app.
