/**********************************************************************
Audacity: A Digital Audio Editor
Tags.h
Dominic Mazzoni
This class holds a few informational tags, such as Title, Author,
etc. that can be associated with a project or other audio file.
It is modeled after the ID3 format for MP3 files, and it can
both import ID3 tags from MP3 files, and export them as well.
It can present the user with a dialog for editing this information.
It only keeps track of the fields that are standard in ID3v1
(title, author, artist, track num, year, genre, and comments),
but it can export both ID3v1 or the newer ID3v2 format. The primary
reason you would want to export ID3v2 tags instead of ID3v1,
since we're not supporting any v2 fields, is that ID3v2 tags are
inserted at the BEGINNING of an mp3 file, which is far more
useful for streaming.
Use of this functionality requires that id3lib be compiled in
with Audacity.
