---------------------------- original notices -------------------------

Contains code from "exifdump.py" originally written by Thierry Bousch
<bousch@topo.math.u-psud.fr> and released into the public domain.

Updated and turned into general-purpose library by Gene Cash

Patch Contributors:
* Simon J. Gerraty <sjg@crufty.net>
s2n fix & orientation decode

Added support for newer Nikon type 3 Makernote format for D70 and some
other Nikon cameras.
* Joerg Schaefer <schaeferj@gmx.net>
Fixed subtle bug when faking an EXIF header, which affected maker notes
using relative offsets, and a fix for Nikon D100.

            Added ability to extract JPEG formatted thumbnail.

            tag name.
            Factored into library returning dictionary of IFDs plus
            thumbnail, if any.
