Inter-chunk communication (in same process)

[xanxys]

Needs serialization / deserialization layer like in real network situation, but no consideration of bandwidth / CPU allocation is necessary.

Don't even think about optimization. Using all grains from all neighbors is totally fine.

This task is probably achieved by:

• Allowing multiple chunks to co-exist (mainly renaming, refactoring)
• Making use of neighbor information when calculating grains

Some form of cross-chunk interaction observed. Let's focus on fixing bugs & visualizing them to confirm fix.
