@desc
Applies a ruthless reset of the symmetry flag for the
flat faces (y-direction) of the cartoon plane. The faces
are given the flag CARTOON_NOSYM, which corresponds to
the GFSYM_NOSYM flag in CartGrid3D. The problem with using
CartGrid3D is that it is used to distinguish either a
symmetry BC or radiation BC -- one or the other is always
chosen. So instead, we assign the grid face an otherwise
unrecognised flag which neither the symmetry routines nor
boundary conditions will respond to. Not a complete solution,
but good enough to get Cartoon running with standard
BSSN configurations.
This routine has to be run after SpatialCoordinates.
