TopoDS_Shape::NbChildren() - new method has been introduced. TopoDS_Shape.lxx, TopoDS_TShape.lxx - inline methods have been moved to hxx. TopoDS_TShape_Flags has been redeclared as enumeration instead of preprocessor macros. Cyclic dependency between headers TopoDS_Shape.hxx and TopoDS_TShape.hxx eliminated. Places where TopoDS_Iterator is used only for calculation of number of sub-shapes are updated to use NbChildren() instead
