Description

Index sorting is currently handled inside Sorter and MultiSorter, with hard-coded implementations dependent on SortField types. This means that you can't sort by custom SortFields, and also that the logic for handling specific sort types is split between several unrelated classes.

SortFields should instead be able to implement their own index sorting methods.
