0031136: Modeling Data - BinXCAF persistence loses normals from triangulation-only Faces

Browse Source 
Information about normals are stored in BinOCAF, XmlOCAF, BRep and BBRep (in case of triangulation-only Faces).
Versions of formats have been changed (11 for TDocStd, 4 for BRep Shape and 3 for Binary BRep Shape)
theWithNormals parameter added to BRepTools::Write()
IsWithNormals()/SetWithNormals() function added to BRepTools_ShapeSet
-normals/-noNormals option added to StoreTriangulation DRAW command
-normals/-noNormals option added to writebrep DRAW command
Tests for writing to brep/binary brep/BinXCaf/XmlXCaf added
Test for StoreTriangulation options -normals/-noNormals added

Information about per-vertex triangulations normals is now stored in BinOCAF and XmlOCAF document,
BRep and Binary BRep Shape formats (only in case of triangulation-only Faces, with no analytical geometry to restore normals).
Versions of formats have been changed (11 for BinOCAF, 10 for XmlOCAF, 4 for BRep Shape and 3 for Binary BRep Shape).
Files written with the new version will not be readable by applications of old versions.
