                     21:  * 
                     22:  * This class uses a 'is-a' relation to KeyFilter in contrast to a 'has-a'
                     23:  * relation. Doing so both current() and key() methods must be overwritten. 
                     24:  * If it would use a 'has-a' relation there would be much more to type...
                     25:  * but for puritists that would allow correctness in so far as then no 
                     26:  * key() would be needed.
