-/*
-* Documentation: Workflow summary for histogram data processing:
-* For more details on FIFO, please see system/media/audio_utils; doxygen
-* TODO: add this documentation to doxygen once it is further developed
-* 1) Writing buffer period timestamp to the circular buffer
-* onWork()
-*     Called every period length (e.g., 4ms)
-*     Calls LOG_HIST_TS
-* LOG_HIST_TS
-*     Hashes file name and line number, and writes single timestamp to buffer
-*     calls NBLOG::Writer::logEventHistTS once
-* NBLOG::Writer::logEventHistTS
-*     calls NBLOG::Writer::log on hash and current timestamp
-*     time is in CLOCK_MONOTONIC converted to ns
-* NBLOG::Writer::log(Event, const void*, size_t)
-*     Initializes Entry, a struct containing one log entry
-*     Entry contains the event type (mEvent), data length (mLength),
-*     and data pointer (mData)
-*     TODO: why mLength (max length of buffer data)  must be <= kMaxLength = 255?
-*     calls NBLOG::Writer::log(Entry *, bool)
-* NBLog::Writer::log(Entry *, bool)
-*     Calls copyEntryDataAt to format data as follows in temp array:
-*     [type][length][data ... ][length]
-*     calls audio_utils_fifo_writer.write on temp
-* audio_utils_fifo_writer.write
-*     calls obtain(), memcpy (reference in doxygen)
-*     returns number of frames written
-* ssize_t audio_utils_fifo_reader::obtain
-*     Determines readable buffer section via pointer arithmetic on reader
-*     and writer pointers
-* Similarly, LOG_AUDIO_STATE() is called by onStateChange whenever audio is
-* turned on or off, and writes this notification to the FIFO.
-*
-* 2) reading the data from shared memory
-* Thread::threadloop()
-*     TODO: add description?
-* NBLog::MergeThread::threadLoop()
-*     calls NBLog::Merger::merge
-* NBLog::Merger::merge
-*     Merges snapshots sorted by timestamp
-*     for each reader in vector of class NamedReader,
-*     callsNamedReader::reader()->getSnapshot
-*     TODO: check whether the rest of this function is relevant
-* NBLog::Reader::getSnapshot
-*     copies snapshot of reader's fifo buffer into its own buffer
-*     calls mFifoReader->obtain to find readable data
-*     sets snapshot.begin() and .end() iterators to boundaries of valid entries
-*     moves the fifo reader index to after the last entry read
-*     in this case, the buffer is in shared memory. in (4), the buffer is private
-*
-* 3) reading the data from private buffer
-* MediaLogService::dump
-*     calls NBLog::Reader::dump(CONSOLE)
-*     The private buffer contains all logs for all readers in shared memory
-* NBLog::Reader::dump(int)
-*     calls getSnapshot on the current reader
-*     calls dump(int, size_t, Snapshot)
-* NBLog::Reader::dump(int, size, snapshot)
-*     iterates through snapshot's events and switches based on their type
-*     (string, timestamp, etc...)
-*     In the case of EVENT_HISTOGRAM_ENTRY_TS, adds a list of timestamp sequences
-*     (histogram entry) to NBLog::mHists
-*     TODO: add every HISTOGRAM_ENTRY_TS to two
-*     circular buffers: one short-term and one long-term (can add even longer-term
-*     structures in the future). When dump is called, print everything currently
-*     in the buffer.
-* NBLog::drawHistogram
-*     input: timestamp array
-*     buckets this to a histogram and prints
