Method to list tags

[GoogleCodeExporter]

There should be a method for listing all tags, so that users can dump the 
Exif metadata from a file and study what's in there to discover new and 
potentially useful tags.

A method like this already exists: MetaInfoRecord.getTagNums() returns a sorted 
list
of all tags in that particular MetaInfoRecord. Of course, in order to use it 
you need
to know which MetaInfoRecords are present within a file.

However, for discovering potentially useful tags, I think it's best just to 
read the
Exif and IPTC specs. But please correct me if I'm wrong.

Hi !
I hope this project is not dead !
I would like such a feature included. Exif infos are 'technical' and IPTC are 
more
human friendly (human infos about the picture).
That's why, it may not look interesting to get the list of EXIF tags (not 
sure), but
for me it is very interesting to get a list of IPTC tags as they are not often
present inside picture and, as it is human friendly, all infos may be 
interesting.

Hope to ear from news soon
