 100
 101 1999-08-21 TB  Last update by Thierry Bousch to his code.
 102
 103 2002-01-17 CEC Discovered code on web.
 104             Commented everything.
 105             Made small code improvements.
 106             Reformatted for readability.
 107
 108 2002-01-19 CEC Added ability to read TIFFs and JFIF-format JPEGs.
 109             Added ability to extract JPEG formatted thumbnail.
 110             Added ability to read GPS IFD (not tested).
 111             Converted IFD data structure to dictionaries indexed by
 112             tag name.
 113             Factored into library returning dictionary of IFDs plus
 114             thumbnail, if any.
 115

 118             Converted data structure to single-level dictionary, avoiding
 119             tag name collisions by prefixing with IFD name.  This makes
 120             it much easier to use.
