[Ifeffit] Build intrinsic defect vacancy structure with doping atom.

Dear Prof. ; Thanks for your great informations about build doping atoms, and now we consider the real intrinsic defect structure for LiNbO3 single crystal, as people know about Nb vacancy (means there is a hole on Nb atom site) can be exist in this crystal, and our question is; The input file is correct or not? ps: because we had not see the relation example, maybe you can remark the mistake on it and e-mail back.
