+   * \brief Get the swap mode of the file.
+   *
+   * Pcap files use a magic number that is overloaded to identify both the 
+   * format of the file itself and the byte ordering of the file.  The magic
+   * number (and all data) is written into the file according to the native
+   * byte ordering of the writing system.  If a reading application reads
+   * the magic number identically (for example 0xa1b2c3d4) then no byte 
+   * swapping is required to correctly interpret the file data.  If the reading
+   * application sees the magic number is byte swapped (for example 0xd4c3b2a1)
+   * then it knows that it needs to byteswap appropriate fields in the format.
+   *
+   * GetSWapMode returns a value indicating whether or not the fields are being
+   * byteswapped.  Used primarily for testing the class itself, but may be 
+   * useful as a flag indicating a difference in endianness of the writing 
+   * system.
