kgv b2d1851c43 0029814: Modeling Data - add method TopoDS_Shape::NbChildren() for simple check of sub-shapes number
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
