QuantumPackage/scripts/save_current_dets.sh
Kevin Gasperich d98bda5b11 save determinants directory when save_wavefunction_general_complex is called
added option to turn this on or off
determinants/backup_determinants_dir (default True)

tars the determinants directory and moves the tar to ezfio/save/determinants/determinants.nstate.ndet.tar
gzip doesn't save any significant space (the large parts are already gzipped)

saves one backup per nstate,ndet pair
