Sorting lists of lists...

    I have a class structure like:

    class image : public list<class element> {};

    class series : public list<class image>
    bool operator< (const image & img) const
    return (image_id < img.image_id);

    class study : public list<class series> {};
    class patient : public list<class study> {};
    class patients : public list<patient> {};

    So sorting the series class is quite simple I just:

    series s;

    An unprocessed series can contain images from different studies and
    different patients.

    --------->>>> What I want to do is go through the series list and build
    up a a sorted patient list.... (patients please!)

    Within each image is a image_id, patient_id, series_id and a study_id.

    What is the best way to build up the patient list?

    I was thinking of modifying the series operator< and add the patient_id,
    study_id series_id, and image_id so that at least that
    list is completly sorted.... Then traverse the series list and populate
    the patient list... (class patients)

    Should I add a operator< to each class?

    What do you think?
