change space_getcell to space_getcells, can pick up more than one cell at a time.

As discussed in #255 (closed). Have only checked that it works, haven't done any benchmarks, but this can only make things faster

Wow, that was swift... thanks !

I'll wait until we have one of the improved sorting branches merged in though.

Added 77 commits:

• 5604c42c...4c7e281b - 76 commits from branch master
• c2f8e1ec - Merge branch 'master' into space_getcell

Status changed to merged
