+/**
+ * @brief Utility class to fetch latest version of the segmented data
+ *
+ * SegmentFetcher assumes that the data is named /<prefix>/<version>/<segment>,
+ * where:
+ * - <prefix> is the specified prefix,
+ * - <version> is an unknown version that needs to be discovered, and
+ * - <segment> is a segment number (number of segments is unknown and is controlled
+ *   by `FinalBlockId` field in at least the last Data packet
+ *
+ * The following logic is implemented in SegmentFetcher:
+ *
+ * 1. Express first interest to discover version:
+ *
+ *    >> Interest: /<prefix>?ChildSelector=1&MustBeFresh=yes
+ *
+ * 2. Infer the latest version of Data:  <version> = Data.getName().get(-2)
+ *
+ * 3. If segment number in the retrieved packet == 0, go to step 5.
+ *
+ * 4. Send Interest for segment 0:
+ *
+ *    >> Interest: /<prefix>/<version>/<segment=0>
+ *
+ * 5. Keep sending Interests for the next segment while the retrieved Data does not have
+ *    FinalBlockId or FinalBlockId != Data.getName().get(-1).
+ *
+ *    >> Interest: /<prefix>/<version>/<segment=(N+1))>
+ *
+ * 6. Fire onCompletion callback with memory block that combines content part from all
+ *    segmented objects.
+ *
+ * If an error occurs during the fetching process, an error callback is fired
+ * with a proper error code.  The following errors are possible:
+ *
+ * - `INTEREST_TIMEOUT`: if any of the Interests times out
+ * - `DATA_HAS_NO_SEGMENT`: if any of the retrieved Data packets don't have segment
+ *   as a last component of the name (not counting implicit digest)
+ * - `SEGMENT_VERIFICATION_FAIL`: if any retrieved segment fails user-provided validation
+ *
+ * In order to validate individual segments, an VerifySegment callback needs to be specified.
+ * If the callback returns false, fetching process is aborted with SEGMENT_VERIFICATION_FAIL.
+ * If data validation is not required, provided DontVerifySegment() functor can be used.
+ *
+ * Examples:
+ *
+ *     void
+ *     onComplete(const ConstBufferPtr& data)
+ *     {
+ *       ...
+ *     }
+ *
+ *     void
+ *     onError(uint32_t errorCode, const std::string& errorMsg)
+ *     {
+ *       ...
+ *     }
+ *
+ *     ...
+ *     SegmentFetcher::fetch(face, Interest("/data/prefix", time::seconds(1000)),
+ *                           DontVerifySegment(),
+ *                           bind(&onComplete, this, _1),
+ *                           bind(&onError, this, _1, _2));
