Functions/Subroutines
double precision function	compute_time_step_cfl_advection (velocity, temporal_stability_factor)
	Compute the time step restricted by the CFL Warning: this is called "advection" refering the the mathematical advection equation Thus we look for the maximum velocity in the whole domain.
