Making IO::out_dir fully steerable is certainly doable but - for
consistency - requires changes in all I/O thorns which share this I/O
parameter. I'd rather limit necessary changes to individual thorns for
now, making their own output/checkpoint directory parameters steerable.
One could start with CarpetIOHDF5 and CarpetIOASCII.
Before implementing anything we should clearly define what should happen
when switching to a different output directory. HDF5 files will surely
be created anew. What about existing ASCII output files, should they
also be split or appended in the old outdir ? Would it suffice to make
the checkpoint directory steerable ?
