relax SVN archive

The optimised rotor axis is recreated with the lib.frame_order.rotor_axis.create_rotor_axis_alpha()
function, and then the original and optimsed axes are compared. The state.save user function has
been shifted forwards in the script to avoid a later RelaxError.

The log file, average position PDB file, and state file from running the script have been added to
the repository or updated.
