>From large tests I got no failures.
The TestReversibleScanners and TestFSHLog that were failing have been fixed in
the latest patch. It was nothing but it needed ChunkCreator to be initialized.
bq.Looks like the above assignment can be moved after currentInstance is
created.
Nope. We need a new type of Chunkcreator so that it is able to retire the
chunks immediately. So we nullify the current Instance and recreate the
chunkCreator instance and again assign the original one back to the INSTANCE
variable. If needed I can rename from 'currentInstance' to 'oldInstance'.

> For CellChunkMap we may need a cell such that the chunk out of which it was
> created, the id of the chunk be embedded in it so that when doing flattening
> we can use the chunk id as a meta data. More details will follow once the
> initial tasks are completed.
> Why we need to embed the chunkid in the Cell is described by [~anastas] in
> this remark over in parent issue
