Aleksey Yeschenko updated CASSANDRA-6933:
-----------------------------------------

    Attachment: 6933-v5.txt

Attaching a bikeshed v5 that makes ABSC#searchIterator() use an anonymous 
class, use the comparator instead of equals, and kills some unused imports 
elsewhere.

> Introduce a new SearchIterator construct, which can be obtained from a 
> ColumnFamily, which permits efficiently iterating a subset of the cells in 
> ascending order. Essentially, it saves the previously visited position and 
> searches from there, but also tries to avoid searching the whole remaining 
> space if possible.
