This routine sets the GH extension (EinsteinBoundGHex *bGHex),
which describes the symmetry boundary type of each GF. Takes
the name of the GF ("implementation::gfname") and the symmetry operators
sx,sy,sz and inserts them in the array bGHex.
These values will looked up by the application routines SymmetryWrappers
