-----------------------------------+----------------------------------------
 currently poison_boundaries causes RotatingSymmetry180 checks for both the
 poison value and for nonfinite values in the boundary. It should probably
 not check for NaN in case there are grid functions that do actually
 contain nan values near the boundaries (right not I have a run where this
 is true for ML_BSSN::H where I don't care about the NaNs).
 RotatingSymmetry's output completely clutters stdout since it list every
 single nan point it find.

 If one wants to check for NaN values in the constraints one can always use
 NaNChecker so no functionality is lost.

 Also RotatingSymmetry might well see NaN values when combined with say
 ReflectionSymmetry if the NaNs would be overwritten by say a z-reflection
 symmetry afterwards (I am not sure what the order in which symmetries are
 applied is).
