0030670: Modeling Algorithms - Performance improvement of Boolean Operations algorithm

Browse Source 
The following improvements have been made in Boolean operations algorithm:
1. Added possibility to update FaceInfo structure for many faces at once which helps to avoid nested loops.
2. Improve Point-Face classification procedure by caching the FaceExplorer for a face.
