A Manifold object based on OpenCASCADE TopoDS_Shape where new points are first computed by averaging the surrounding points in the same way as FlatManifold does, and are then projected in the normal direction using OpenCASCADE utilities.
This class makes no assumptions on the shape you pass to it, and the topological dimension of the Manifold is inferred from the TopoDS_Shape itself. In debug mode there is a sanity check to make sure that the surrounding points (the ones used in project_to_manifold()) actually live on the Manifold, i.e., calling OpenCASCADE::closest_point() on those points leaves them untouched. If this is not the case, an ExcPointNotOnManifold is thrown.
This could happen, for example, if you are trying to use a shape of type TopoDS_Edge when projecting on a face. In this case, the vertices of the face would be collapsed to the edge, and your surrounding points would not be lying on the given shape, raising an exception.
