### New features

- For strong STG, element size is calculated from cell-to-face basis. `-stg_dx` no longer needed in that case.
- Add projection of the divergence of diffusive flux for Navier-Stokes equations, see !27
- Add sine and square wave initial conditions for advection-diffusion example, see !38
- Add diffusion component of stabilization tau formulation for advection-diffusion, see !42
- Add projection of the divergence of diffusive flux for advection-diffusion equations, see !43
- Add boundary layer IC and wind type to advection-diffusion equations, see !46
