+ * Use Case 1.7 Appending a single chunk
+ * Description:
+ * Appending a single chunk of raw data to a dataset along an unlimited
+ * dimension within a pre-created file and reading the new data back.
+ * Goal:
+ * Read data appended by the Writer to a pre-existing dataset in a
+ * file. The dataset has one or more unlimited dimensions. The data is
+ * appended by a hyperslab that is contained in one chunk (for example,
+ * appending 2-dim planes along the slowest changing dimension in the
+ * 3-dim dataset).
+ * Level:
+ * User Level
+ * Guarantees:
+ * o Readers will see the modified dimension sizes after the Writer
+ * finishes HDF5 metadata updates and issues H5Fflush or H5Oflush calls.
+ * o Readers will see newly appended data after the Writer finishes
+ * the flush operation.
+ *
+ * Preconditions:
+ * o Readers are not allowed to modify the file.
+ * o All datasets that are modified by the Writer exist when the Writer
+ * opens the file.
+ * o All datasets that are modified by the Writer exist when a Reader
+ * opens the file.
+ * o Data is written by a hyperslab contained in one chunk.
+ *
+ * Main Success Scenario:
+ * 1. An application creates a file with required objects (groups,
+ * datasets, and attributes).
+ * 2. The Writer application opens the file and datasets in the file
+ * and starts adding data along the unlimited dimension using a hyperslab
+ * selection that corresponds to an HDF5 chunk.
+ * 3. A Reader opens the file and a dataset in a file, and queries
+ * the sizes of the dataset; if the extent of the dataset has changed,
+ * reads the appended data back.
+ *
+ * Discussion points:
+ * 1. Since the new data is written to the file, and metadata update
+ * operation of adding pointer to the newly written chunk is atomic and
+ * happens after the chunk is on the disk, only two things may happen
+ * to the Reader:
+ * o The Reader will not see new data.
+ * o The Reader will see all new data written by Writer.
