Class that will force an index writer to open an index based on the generation in the segments.gen file as opposed to the highest generation found in a directory listing. A use case for using this IndexCommit when opening an IndexWriter would be if index snapshots (source) are being copied over an existing index (target) and the source now has a lower generation than the target due to initiating a rebuild of the index.
