support mesh refined grid scalars and grid arrays

Issue #2047 new
Roland Haas created an issue

Every once in a while it would be useful if one had access to scalar/array variables for which there was one copy per refinement level and that may or may not restrict from the fine into the coarse levels.

Examples are * evolving particles along with the fields (restriction would happen) if there is actual back-and-forth interaction between particles and fields (ie not just tracers) * keeping track of a reduced quantity on a per-reflevel basis (eg. number of times RHS was evaluated for this level), not restriction in this case

    CarpetLib supports arbitrary AMR hierarchies for all variables. Carpet's Cactus interface does not. The best way to implement this would probably be to define a new type of grid variable (currently: scalar, array, gf).
