------------------------------------------------

Yes you are correct here. We now try to avoid that copy when we move from 
active to immutable segment. If we have chunk id we could directly use that as 
the pointer as to where the cell resides.

> Create a cell type so that chunk id is embedded in it

> 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.
