23.05.06:
[ ] Implemented basic OGG player
[ ] Implemented positioning inside a song (need to verify if reliable and deterministic!)
[ ] Researched BPM analysers. MixMeister BPMAnalyzer is very good. Tapping is also
    an option.

24.05.06:
[ ] Started marker implementation
[ ] Implemented screen fading to have some visuals for marker events
[ ] Started working on editor and found out that I need to think more about
    track organisation, packages and so on. So will stop coding and do a bit
    of design.

25.05.06:
[ ] Finished first implementation of marker events
[ ] Very rough implementation of tapping, packages, tracks and editor
[ ] Recording of marker events works
[ ] Fast forward and rewind works. (Still a bug when fast forwarding past the
    end of the song).
[ ] Implemented crosshair for picking stuff on screen.
[ ] Decided on using Boost for serialisation (= save/load) of packages. Then
    the SourceForge server died on me when I wanted to download the library :(
