       Audio::File::Tag is the base class for other file format independent tag classes like
       Audio::File::Flac::Tag or Audio::File::Ogg::Tag. You shouldn't use this class yourself except if you're
       writing your own file format dependent subclass.

new
       Constructor. Creates a new Audio::File::Tag object. You shouldn't use this method yourself. It is called
       by the filetype-dependant subclasses of Audio::File::Type automatically.

   init
       Initializes the object. It's called by the constructor and empty by default.  It's ought to be
       overwritten by subclasses.

   title
       Using title() you can get or set the tags title field. If called without any argument it'll return the
       current content of the title field. If you call title() with an scalar argument it will set the title
       field to what the argument contains. The methods artist(), album(), comment(), genre(), year(), track(),
       disc() and total() are called in the same way.

   artist
       Set/get the artist field in the files tag.

   album
       Set/get the album field in the files tag.

   comment
       Set/get the comment field in the files tag.

   genre
       Set/get the genre field in the files tag.

   year
       Set/get the year field in the files tag.

   track
       Set/get the track field in the files tag.

   disc
       Set/get the disc field in the files tag.

   total
       Set/get the total number of tracks.

   all
       Set/get all tags. To set the tags pass a hash reference with the names of the tags as keys and the tag
       values as hash values. Returns a hash reference if no argument is specified.

   is_empty
       Returns whether all tag fields are empty or not.

   save
       Saves the changed tag information. Not yet implemented.
