    Duplicate of groupBy. Not word for word, but the concept isn't novel.

    Or is it different enough?

    So what's the idea?.. Now grouping by a given key works as well as grouping by id reset.

      This is an idea I had from something I did at work, I used the numbered id, a colleague used the key, so thought to leave both possibilities as an option to the reader here

    but each category will only occur once, there won't be repetitions afterwards.

     has the right amount of categories
