Subroutines

subroutine standard_tpo_to_bssn(l, nx, ny, nz, dx, dy, dz, ngx, ngy, ngz, gxx, gxy, gxz, gyy, gyz, gzz, kxx, kxy, kxz, kyy, kyz, kzz, alp, betax, betay, betaz, dtalp, dtbetax, dtbetay, dtbetaz, r)

Compute the BSSN variables starting from the standard 3+1 (aka ADM) variables This is basically a version of ADM_to_BSSN from MODULE McLachlan_refine that allows for array arguments.
