* @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.
