IdSets assign some orderable, unique identifier to all entities in the grid. As a first step towards making intersections first class citizens in dune, I suggest to assign ids to intersections.
This also has an impact on the boundarySegmentIndex discussion. As indices, they will not be valid during load balancing and users need some way of storing their data during this period. While boundary segments must coincide with a codim-1 entity (except for the periodic case in AlbertaGrid, ALUGrid, and SPGrid), I think this is the cleaner approach.
For most grids, intersections will coincide with some entity in the grid, so this interface addition should not be too much work (except maybe for UGGrid).
