I. New features:
I.1 class BOPAlgo_Section
The class clontains the algorithm to build a result of Secton between the arguments.
The result of Section consists of vertices and edges.
The result of Section contains:
1. new vertices that are subjects of V/V, E/E, E/F, F/F interferences
2. vertices that are subjects of V/E, V/F interferences
3. new edges that are subjects of F/F interferences
4. edges that are Common Blocks
5.a vertex is included in result of Section only when it is not shared
between the edges of the result of Section
The class BOPAlgo_Section inherits the functionality of root class BOPAlgo_Builder

Performs fast BVH construction using LBVH building approach. Algorithm uses spatial Morton codes to reduce the BVH construction problem to a sorting problem (radix sort -- O(N) complexity).
