writing subsets of grids in code not working w/o copy

[ipelupessy]

the following works:

from amuse.io import write_set_to_file
from amuse.datamodel import Grid
g=Grid(10,10,10)
g.z=1
sg=g[1:5,2:5,:]
write_set_to_file(sg,"subgrid","amuse")

but the write_set_to_file seems to break when sg is a subgrid of an in-code grid, you need sg.copy() first...

[ipelupessy]

needs to be checked
