We (me and Johan Jansson) have implemented a bisection mesh refinement
algorithm that is dimension independent, and also a mesh coarsening
algorithm that is dimension independent. Johan has also implemented a
general projection operator that projects a function from one
mesh+function space to another mesh+function space. These algorithms
appear to be in good shape. What is needed is some more testing, cleaning
up, and a demo, which is under way.

I have also implemented a class for a hierarchy of meshes, and started to
re-implement the old Bey-algorithm for this structure.

On the mesh refinement/coarsening todo-list we next have: edge-flip and
face-swaps, and finishing the Bey-algorithm. We are also working on some
mesh smoothing algorithms together with Michael Stöckli.
