Hi - it looks like the tools/grid_refine.py tool has not been updated to
use the newer grid file format
used by the read_grid, write_grid, adapt_grid, and fix_adapt commands.

So we can update the python file to use the common format.

Re: rotation, I'm not sure what you mean.  Do you mean in the context of
grid adaptation?
Or just to include rotation effects in collisions?
