On occasion, you may need to unregister or retrieve a plugin. The following methods of the front controller allow you to do so:
getPlugin($class)allows you to retrieve a plugin by class name. If no plugins match, it returnsFALSE. If more than one plugin of that class is registered, it returns an array.getPlugins()retrieves the entire plugin stack.unregisterPlugin($plugin)allows you to remove a plugin from the stack. You may pass a plugin object, or the class name of the plugin you wish to unregister. If you pass the class name, any plugins of that class will be removed.
