use more general annotations, not only stages
restructure widgets around, for clarify
much better order in creation, now you can update position and toolbars
remember position and geometry in preferences
load and create annotations xml
call bookmark markers instead
use the power of Qt to remember the widgets and show/hide them
remove unused function for toggling dockwidgets
rename bookmarks to markers
improve labels
use bound methods for toolbars
add and remove raters robustly
added icons for markers and events
toolbar for marking and sleep scoring
reset time at zero when you load a new dataset
update overview and keep scores. Markers and events should be treated in a similar way
it creates markers, and you can add them too, but not delete them
create a nice list of markers
use annotations in the dataset
short string when name is too long, and take care that markers are updated when reading the dataset
