void set_grid	(	int	whichtime,
		FTYPE *	CUf,
		FTYPE *	Cunew
	)

GODMARK: may want to make grid functions explicitly 2D for axisymmetric space-times when in axisymmetry with space-time axis aligned with grid.

set up all grid functions

whichtime: 0: setting initial coordinate and metric quantities. Can be called many times to solve initial value problem of coupled matter-metric system of equations. Should NOT be treated as a single call for entire simulation. 1: Setting a future metric such that old metric can be used to compute connection with temporal changes incorporated

CUf/Cunew: time-step for substeps used to iterate the metric and store into old metric when can take temporal difference and use as slope for present value of connection calculation
