Notes
Requirements:
- Steve: FunWave, need parallelism and mesh refinement;
- Ian: 6-variable, linear elliptic equation, need mesh refinement and perhaps parallelism;
- Eloisa: generic solver, easy to use and to experiment with more important than efficiency, no restriction on topology, mesh refinement would be good but doesn't need it for everything;
