 * 2. bootstrap/conf.php1
 *    sets up configuration settings and connects to database
 *    
 * 3. load all core classes
 *    loads core entitys representing the data in the program
 *
 * 4. load security classes
 *	  load up password compatability classes and etc
 *
 * 5. load all services 
 *    load up services that operate on the data that can be called from controllers
