The save file created by the frame order test data generation base script can now be bypassed.
When loading 1,000,000 PDB structures as models into the relax data store, the RAM usage can go over
10 Gb. When trying to save this into a relax state file with the state.save user function, the time
required can be over a day. Therefore the SAVE_STATE class variable has been introduced to allow
the state.save call to be bypassed.
