/**
* Call a hook with a given name
*
* Checks if a hook with the given name and for the current task
* exists and executes it. The name of the current task is taken
* from the current class name by lower casing the first char.
* This function will execute all registered hooks in the order
* they were registered.
*
* Attention: as func_get_arg() cannot handle references passed to the hook,
* callHook() should not be called if that is required. In that case get
* a list of hook objects with getHookObjects() and call the hooks yourself.
*
* @params string $hook name of hook
* @return string concatenated string, merged arrays or whatever the hook
* function returns
