Simple subdomains handler for CI3

All I'm saying is that users will find this thread and see "Simple subdomain handler for CI3" and think your initial post is the correct way to handle subdomains, which it isn't. It may work for you in your application, because you added additional checks and hacked around the issue of valid/invalid users on sub domains, but others should be warned that the above method is not a plug-n-play or secure way of doing things.
