-/**
- * A group of writes that will be applied together atomically to persistent storage.
- *
- * This class is usable by both Objective-C and Objective-C++ clients. Objective-C clients are able
- * to create a new group and commit it. Objective-C++ clients can additionally add to the group
- * using deleteKey: and putKey:value:.
- *
- * Note that this is a write "group" even though the underlying LevelDB concept is a write "batch"
- * because Firestore already has a concept of mutation batches, which are user-specified groups of
- * changes. This means that an FSTWriteGroup may contain the application of multiple user-specified
- * mutation batches.
