0033 //! Any  new type  of  constrained boundary must inherit this class.
0034 //! The GeomFill package provides two classes to define constrained boundaries:
0035 //! -   GeomFill_SimpleBound to define an unattached boundary
0036 //! -   GeomFill_BoundWithSurf to define a boundary attached to a surface.
0037 //! These objects are used to define the boundaries for a
0038 //! GeomFill_ConstrainedFilling framework.
