/**
* ProcessWire Installer
*
* Because this installer runs before PW2 is installed, it is largely self contained.
* It's a quick-n-simple single purpose script that's designed to run once, and it should be deleted after installation.
* This file self-executes using code found at the bottom of the file, under the Installer class.
*
* Note that it creates this file once installation is completed: /site/assets/installed.php
* If that file exists, the installer will not run. So if you need to re-run this installer for any
* reason, then you'll want to delete that file. This was implemented just in case someone doesn't delete the installer.
