DAMultiplyByJacobian1WithAdic

Applies an ADIC-provided Jacobian function to a vector on each processor that shares a DA.

#include "petscda.h"   
int DAMultiplyByJacobian1WithAdic(DA da,Vec vu,Vec v,Vec f,void *w)

	da	- the DA that defines the grid
	vu	- Jacobian is computed at this point (ghosted)
	v	- product is done on this vector (ghosted)
	fu	- output vector = J(vu)*v (not ghosted)
	w	- any user data

This routine does NOT do ghost updates on vu upon entry.
