+ * @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.
