This Script Creates a new User who is added to the sudo group. It then does the following:

1) Places the new user's SSH key into their .ssh/authorized_keys folder to allow for logging in with the public key
2) Disables Root Login
3) Disables Password Authentication

This should work on any Linux distribution.

Compatible with: CentOS 7, CentOS 6.8, Ubuntu 14.04 LTS
