Motivation:

When I read the source code, I found that the comment of PoolChunk is out of date, it may confuses readers with the description about memoryMap.

Modifications:

update the last passage of the comment of the PoolChunk class.

No change to any source code , just update comment.

* Note:
* -----
* In the implementation for improving cache coherence,
* we store 2 pieces of information (i.e, 2 byte vals) as a short value in memoryMap
* we store 2 pieces of information depth_of_id and x as two byte values in memoryMap and depthMap respectively
*
* memoryMap[id]= (depth_of_id, x)
* where as per convention defined above
* the second value (i.e, x) indicates that the first node which is free to be allocated is at depth x (from root)
* memoryMap[id]= depth_of_id is defined above
* depthMap[id]= x indicates that the first node which is free to be allocated is at depth x (from root)
