Dynamic ranking functions in dataview layout

    At the moment the ranking functions are computed once for the dataview and only recomputed when the screen is refreshed. I'd like to have them dynamic. They should be updated whenever the sorting is changed by the user.

    So the cumulated values are computed as expected by the user. That would also allow finding out whether rows are odd or even. Obviously I'd expect values from algorithms and nexel to be recomputed as a result of the change, but the first one would already be nice.
