Hello, I have a question on implementing the Laplace-Beltrami operator in 
FFC/DOLFIN.  Can you do it?  If the domain is just a 2-D surface, then 
maybe not; 2-D topological meshes in 3-D geometric space still needs to be 
implemented right?

What about if I just have a 2-D (flat) domain with a 1-D boundary.  Is 
there a convenient way to define the surface (tangential) gradient in FFC? 
It is just the derivative with respect to arc-length multiplied by the 
tangent vector.  Can you define forms on the boundary like that?
