0025039: Improvement of code structure of general and supporting tools implemented in BRepMesh
Removed CDL declarations; Data collections are replaced by NCollections; Small code refactoring. Remove definition of BRepMesh class. Code refactoring of BRepMesh_IncrementalMesh. Function BRepMesh_Write storing BRepMesh_DataStructureOfDelaun to BRep file is added for debug needs. Static method BRepMesh_GeomTool::IntLinLin has been added to eliminate code duplications in BRepMesh_Dealun and BRepMesh_CircleTool. BRepMesh_CircleTool simplified method to find circumcircle. Fix merging conflicts Remove redundant function Fix compilation warning on MacOS Revert changes occurred during rebase Resolved merging conflicts Use parallel flag with BRepMesh_FastDiscret Test cases for issue CR25039_2
