Kosztorysant comes back years later

To calculate the cost of a study, it had a sample selection algorithm built in, driven by parameters set in the UI.

The company I work for was taken over, and that's how, years later, I ended up back at the one where I had written Kosztorysant. Imagine my surprise when it turned out they were using it to select samples for their studies, because they had noticed that the saved file contains a selected sample.

The algorithm was good enough to be put to use in this funny way :-)
