Specialization of Boundary<dim,spacedim>, which places the new point right into the middle of the given points. The middle is defined as the arithmetic mean of the points.
This class does not really describe a boundary in the usual sense. By placing new points in the middle of old ones, it rather assumes that the boundary of the domain is given by the polygon/polyhedron defined by the boundary of the initial coarse triangulation.

Given a candidate point and a line segment characterized by the iterator, return a point that lies on the surface described by this object. This function is used in some mesh smoothing algorithms that try to move around points in order to improve the mesh quality but need to ensure that points that were on the boundary remain on the boundary.
The point returned is the projection of the candidate point onto the line through the two vertices of the given line iterator.
If spacedim==1, then the line represented by the line iterator is the entire space (i.e. it is a cell, not a part of the boundary), and the returned point equals the given input point.

Same function as above but for a point that is to be projected onto the area characterized by the given quad.
The point returned is the projection of the candidate point onto the bilinear surface spanned by the four vertices of the given quad iterator.
If spacedim<=2, then the surface represented by the quad iterator is the entire space (i.e. it is a cell, not a part of the boundary), and the returned point equals the given input point.

Same function as above but for a point that is to be projected onto the area characterized by the given quad.
The point returned is the projection of the candidate point onto the trilinear manifold spanned by the eight vertices of the given hex iterator.
If spacedim<=3, then the manifold represented by the hex iterator is the entire space (i.e. it is a cell, not a part of the boundary), and the returned point equals the given input point.
