Yes, a good place to start would be to think about how to extend the
Mesh class to do higher order meshes.

It has been the plan all the way to support higher order meshes. The
Mesh consists basically or two things: MeshTopology and MeshGeometry.
The MeshGeometry class is very simple and just contains a list of
vertex coordinates. One could think of either extending this class
or having separate implementations handle different type meshes.
