Atom-filtering

Hello people.

I've tried to find something like atom-filtering on the interwebs, but it
does not seems to be anything like this available.

So: here is my attempt for creating a atom-filter extension:

Please send any comments, recommendations.

Please also look at the examples in the Appendix for which one would be
preferred.


Best regards
