Overlaps/Intersections diagnostics - Dual Domain models

The Overlaps/Intersections diagnostic process has been significantly sped up.

Speed improvements of up to four times the 2015 rate has been found on Dual Domain models with over 100 thousand elements. Editing the mesh while the diagnostic is running has also resulted in a significant speed improvement.

There is a better detection of overlapping elements including the interaction with baffles and beam elements.
