Spatial Querying: Implementation of BVH tree for IFC files using NCollection_UBTree (#130)

Browse Source 
* Implementation of BVH tree for IFC files using NCollection_UBTree

* Fixes for gcc and OCCT < v6.8

* Enable BVH selection by TopoDS_Shape

* Small fixes to tree

* Merge conflicted files and other changes

* Eliminate one warning (some remain) + add tree test
