TSSetCFLTimeLocal

Set the local CFL constraint relative to forward Euler

#include "petscts.h"  
PetscErrorCode TSSetCFLTimeLocal(TS ts,PetscReal cfltime)

Logically Collective on TS

	ts	- time stepping context
	cfltime	- maximum stable time step if using forward Euler (value can be different on each process)

After calling this function, the global CFL time can be obtained by calling TSGetCFLTime()
