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
