+ Changed signature of SliceInformation supporting WriteBackSegmentationResult to
WriteBackSegmentationResults (needed to avoid now compiler errors due to implicit parameter conversion).
+ Aligned behavior of WriteBackSegmentationResults to the behavior of
other WriteBackSegmentationResult overloads. Until now WriteBackSegmentationResults had a complete different implementation that. No it is streamlined and WriteBackSegmentationResult overloads all call WriteBackSegmentationResults and all behave like the former WriteBackSegmentationResult(const PlaneGeometry* ...) version.
+ Made SliceInformation element const to avoid unintended manipulation.
+ improved const correctness
+ refactored redundant code into own function (RemoveContourFromInterpolator)
+ added UpdateSurfaceInterpolation overload to support the processing of
a SliceInformation vector at once.
+ Reworked LiveWireTool2D to use the new reworked WriteBackSegmentationResults
+ Fixed internal "bug"/inconsistency in working slice generation in LiveWireTool2D.
Problem was not obvious/relevant so far, because the bug got covered by an other effect (maybe that was the reason of the very "special" own implementation of the slice writing...). Would become a problem as soon as LiveWireTool2D should e.g. correctly support Undo/Do.
