What surface_mesher can do is take the existing polyhedron and given 
criteria functor, it will take points on that polyhedron to produce a 
mesh satisfying the criteria.
It cannot mesh the polyhedron with other points given as input.
Is it important that you select which are the final mesh points? can't
you do that directly by defining a mesh criteria and let the surface
mesher work?
