Hello 3D Slicer team!  
I am a little bit confused with the absolute and signed closest point in model to model distance extension. Can you please explain me what is the difference between those two?

See more details in the [extension documentation](https://www.slicer.org/wiki/Documentation/Nightly/Extensions/ModelToModelDistance) and definite answer in the [source code](https://github.com/NIRALUser/3DMetricTools/blob/master/ModelToModelDistance/ModelToModelDistance.cxx#L209-L249).
