TSInterpolate

Interpolate the solution computed during the previous step to an arbitrary location in the interval

#include "petscts.h"  
PetscErrorCode TSInterpolate(TS ts,PetscReal t,Vec U)

Collective on TS

	ts	- time stepping context
	t	- time to interpolate to

U -state at given time

The user should call TSSetRetainStages() before taking a step in which interpolation will be requested.

TSInterpolate() and the storing of previous steps/stages should be generalized to support delay differential equations and continuous adjoints.
