      @brief Return an auto-pointer to a newly created empty MakerNote
             initialized to operate in the memory management model indicated.
             The caller owns this copy and the auto-pointer ensures that it
             will be deleted.
      
      @param alloc Memory management model for the new MakerNote. Determines if
             memory required to store data should be allocated and deallocated
             (true) or not (false). If false, only pointers to the buffer
             provided to read() will be kept. See Ifd for more background on
             this concept.
      @param buf Pointer to the makernote character buffer (not used). 
      @param len Length of the makernote character buffer (not used). 
      @param byteOrder Byte order in which the Exif data (and possibly the 
             makernote) is encoded (not used).
      @param offset Offset from the start of the TIFF header of the makernote
             buffer (not used).
      
      @return An auto-pointer to a newly created empty MakerNote. The caller
             owns this copy and the auto-pointer ensures that it will be
             deleted.
