Previously there was no easy and documented way to generate an

entire exact spacetime (not just a t=0 slice).  (The "slice_evolver.tex"
stuff might may be able to do this, but it looks complicated. :( )

This change adds this feature (and removes it from the TODO):
just set    ADMBase::evolution_method = "exact"

Thanks to Peter Diener for implementing this!  (It turned out to
be unexpectedly easy: just re-schedule the appropriate setup routine
in CCTK_PRESTEP at each slice!)
