A very simple FileHandler which loads and displays the EXIF meta data of JPEG image files.
Such data is commonly placed in the image files by the image producer such as a digital camera and gives information about when the picture was taken, what camera settings were in use and various other data.
EXIF is an extensible standard and thus this FileHandler cannot know about all kinds of data it might encounter in an image. Such data will be displayed in a binary form.
The FileHandler is a pure viewer and thus doesn't support any modification of the loaded data or saving it in any form.
