Only the constification was really necessary. Actually. The error message was:
"cannot convert 'this' pointer from 'const MeshSurface::MeshTraits' 
to 'MeshSurface::MeshTraits&'". It means that the compiler cannot convert an 
object of type:
  const MeshTraits
to:
  MeshTraits&
The major difference between the two types it the const. Most probably the 
operator() of MeshIntersect need to take the "surface" argument as const.

Log message:

Remove an old piece of code that has been superseded by CGAL code in
