/** @file example4.cpp Test case to demonstrate a subset of the API functions each work correctly.
 *
 * Test case created from Issue 10 code supplied by Motti Gondabi. The code:
 * - creates a KV
 * - writes the KV
 * - closes the KV
 * - flushes the KV
 * - opens the KV.
 * - deletes the KV.
 * - flushes empty configuration store.
 *
 * The test case makes sure that the implementation can flush an empty configuration store
 * without causing errors. This has only been possible since flash-journal-strategy-sequential
 * v0.4.0.
