I will expose getNewestAccessRelation and replace all uses (only in 2 files outside the ScopInfo itself, at the moment).

I cannot see any reason not to use the newest access function except in the dependence analysi but the importer runs after that pass and nobody else (at least for now) uses the functionality of a new access relation anyway.

Thanks!
