Description

Some methods of the IndexBuildManager and IndexBuilder classes return a collection of pairs or triplets (implemented as pairs of pair and single). This makes the Indexer and especially IndexRegionObserver code difficult to read. We can replace the pair structures with a class, say IndexUpdate to make the code more readable.
