OK. I had a quick look last night but it wasn't as straightforward as I 
had anticipated since the mesh is not easily accessible.

Would it make sense to have

   void compute_vertex_values(const Mesh& mesh, double* vertex_values) 
const;

?

One could then use a mesh which is different to the one associated with 
a Function. This is useful when visualising higher-order functions.
