Logically Collective

	dm	- DM to associate callback with
	imode	- insert mode for the residual
	func	- local residual evaluation
	ctx	- optional context for local residual evaluation

func(DMDALocalInfo info,PetscReal t,void *x,void *f,void *ctx)

	info	- DMDALocalInfo defining the subdomain to evaluate the residual on
	t	- time at which to evaluate residual
	x	- array of local state information
	f	- output array of local residual information
	ctx	- optional user context
