Demo for effective boundary saving in regular grid

 
Synopsis
        sfTesteb < Fv.rsf > Fw1.rsf back=Fw2.rsf nb=20 nt= dt= fm=20.0 ft=0 jt=1 ns=1 ng=nx
The sponge absorbing boundary condition is applied for simplicity!
2N-order FD: effective boundary needs N points on each side!
Note: In this demo, 2N=4 (N=2).
