Fix spring/self command

http://www.52souji.net/lammps-command-fix.html WebTo do this, the thermostat and barostat fixes create their own computes of style “temp” and “pressure”, as if one of these sets of commands had been issued: For fix nvt: compute fix-ID_temp group-ID temp. For fix npt and fix nph: compute fix-ID_temp all temp compute fix-ID_press all pressure fix-ID_temp.
