Using volume clip would improve timing for creating labels

Important detail is that VolumeClip will not work when points are in-plane (which is common for prostate MRI annotation). It will be important to either warn the user about this, or have an alternative mechanism to create an in-plane label when all points are in one plane (this would probably make sense to add to VolumeClip directly).

We have a greatly improved version of the markups to model algorithm, which takes care of having all the points being in the same plane and other things. It is implemented in the markups to model module in SlicerIGT extension. I don't know if making SlicerProstate depend on SlicerIGT would be acceptable or we should move the Markups to model module in the Slicer core or find some other solution.

@lassoan Since we are anyway planning to integrate the SegmentEditor in mpReview, we will have to wait until the VolumeClip effect is ready.

For SliceTracker I implemented a module called VolumeClipToLabel:

@lassoan can you clarify - does it still make sense to integrate VolumeClip as a SegmentEditor effect, or it is superseded by the functionality you discussed available in SlicerIGT?

[lassoan]

SlicerIGT contains robust point to surface generation algorithm (and GUI for applying it for model node generation from markup node). It may make sense to make it available in the Slicer core as such functionality is quite often needed. If the algorithm is in the Slicer core then all acripted modules, segment editor effects, etc. could use it.

[lassoan]

Making the algorithm available as a Segment editor effect would be still useful (users would not need to go through several modules to define a segment with points).
