/** @ingroup Examples
 * @brief   Class to iterate all groups within an ini file.
 * @author  Marcus Boerger
 * @version 1.1
 *
 * Using this class you can iterator over all groups of a ini file.
 * 
 * This class uses a 'is-a' relation to KeyFilter in contrast to a 'has-a'
 * relation. Doing so both current() and key() methods must be overwritten. 
 * If it would use a 'has-a' relation there would be much more to type...
 * but for puritists that would allow correctness in so far as then no 
 * key() would be needed.
