Hi,

Running the example code given by Anders to generate a mesh function I
get:

AttributeError: 'UnitSquare' object has no attribute
'create_mesh_function'

This is using the newest fenics from the PPA.

Another question is what to call the mesh function. The data coming from
gmsh has no specific meaning, it is simply an identifier that the FEM
code can do anything with. One obvious application would be the
identification of materials, but it could conceivably also be used to
indicate a solution method to apply, indication of a boundary condition
to apply (when defined on facets) etc.

I would simply call it "group id" or similar. thoughts?
