Changes:
- Documentation completed and a Mini Tutorial added
- Interface changes:
- Test if a value for a tag can be saved is now done in
MiniExiftool#save
=> There is no check at the moment you set a value:
the tag occurs in MiniExiftool#changed_values
=> While calling MiniExiftool#save errors can occur (see next point)
- MiniExiftool#save is a transaction: if one or more error occurs the
file is not changed! In such a case the errors can be found in
MiniExiftool#errors
- Parameter opts of MiniExiftool.initialize is now a Hash with two
options:
- :numerical => read metadata as numerical values
- :composite => read also composite tags
- Tests added
