 The (not usually used) "radiative" boundary condition uses the
 gt11_bound_limit etc to specify the limit of the fields at large radii.
 However right now the defaults for gt11, gt22, gt33 are all zero which is
 rather useless. I know that default values are not "sensible" values but
 rather "historical" values, but I question at which point in time it made
 sense to have the diagonal elements of the metric that we assume to become
 Minkowsky (since phi->0) would tend to zero.
