Checks for root/non-root/sudo

Browse source 
Checks if script is running as root, non-root, or sudo. For root, it sets SUDO variable to nothing and the script runs. If it's not root, then it checks to see if sudo is installed. If it is installed, then it sets SUDO variable to 'sudo' and the script runs. If it is not root and sudo is not installed, then the user does not have sufficient privileges to run the installer and it exits.
