* Addons are registered with the system through the admin

* When registration is detected, the system calls the addon
* name_install() function, located in 'addon/name/name.php',
* where 'name' is the name of the addon.
* If the addon is removed from the configuration list, the
* system will call the name_uninstall() function.
