Class TopTools_MutexForShapeProvider has been created
Class contain methods:
TopTools_MutexForShapeProvider::CreateMutexesForSubShapes - Creates and associates mutexes with each sub-shape of type theType in theShape.
TopTools_MutexForShapeProvider::CreateMutexForShape - Creates and associates mutex with theShape
TopTools_MutexForShapeProvider::GetMutex - Returns pointer to mutex associated with theShape. In case when mutex not found returns NULL.
Added method RemoveAllMutexes to TopTools_MutexForShapeProvider
Assign operator in MutexProvider, constructor and operator and assign operator in Standard_Mutex now private
Replaced TopExp_Explorer with TopoDS_Iterator to avoid cyclic dependence
BRepMesh_Delaun class has been corrected
Extended checking of segments intersection
SquareModulus is used
Detail checking of intersection
Zero division checking
Right segment intersection in MeshPolygon + coding standard
eliminating the test variable
Cleaning up the polygon from internal triangles
