/**
* class which gives ability for applications to set and use hooks to communicate with each other
*
* Hooks need to be declared in the app's setup.inc.php file and they have to be registered
* (copied into the database) by
* - installing or updating the app via setup or
* - running Admin >> register all hooks
* As the hooks-class can get cached in the session (session-type PHP_RESTORE), you also have to log
* out and in again, that your changes take effect.
*
* Hooks can either have two formats
* - new method hooks (prefered), which are methods of a class. You can pass parameters to the call and
* they can return values. They get declared in setup.inc.php as:
* $setup_info['appname']['hooks']['location'] = 'app.class.method';
* - old type, which are included files. Values can only be passed by global values and they cant return anything.
* Old declaration in setup.inc.php:
* $setup_info['appname']['hooks'][] = 'location';
*
* @author Dan Kuykendall
* @author Ralf Becker <RalfBecker@outdoor-training.de> new method hooks
