/**
 * This is the base installer for CiiMS
 * By default, this bootstraps protected/modules/install/installer.php for the initial installation
 * and configuration for Yii. After that, it passes controller to Yii::createWebApplication so that
 * We can run a better install (migrations, config writing, etc...)
 *
 * If you want to make any changes to the PRE YiiPath install, edit /protected/modules/install/installer.php
 * Otherwise, this is a basic Yii App running only the install module
