At the moment the data node selection behavior is rather nasty and cumbersome. The segmentation plugin always tries to do automated node selection which is often confusing from user point of view.
Additional the code which realized this auto selection is very confusing and hence near not maintainable.
- Clean up code for auto selection
- Add new preference which allows the user to enable/disable autoselection
- Add new datastorage selection box for segmentation to specify selected patient and segmentation image
