Did a lot of work regarding the reading of the file. THe interface has
now slightly changed, which will be more clean and neat. There is
unfortunately one point that is not so clear, and the code should be
reviewed and revised. The track is read now, the only thing that needs
to be done now is reading of the individual bytes and the reading part
will also be done. This will mark a milestone and will mark that the
library is ready for a release, after some revisions of course.
