Commit message

thread matrix assembly part for Advection_Diffusion_DG and Advection_Diffusion_FV.

Description of the change

1. thread the matrix assembly for Advection_diffusion_DG, currently not support MASSLUMPED_RT0 diffusion scheme, I simply set threads back to 1 if MASSLUMPED_RT0 diffusion scheme is being used.

2, thread the matrix assembly for Advection_diffusion_FV

Looks good to me. Don't think Advection_diffusion_FV is used much (and if so what for), but threading it doesn't hurt.
