Updated the chi2 check in the Frame_order.test_rigid_data_to_free_rotor_model system test.

This value has changed due to the first 1000 points of the Sobol' sequence being skipped.

Fix for all of the Frame_order.test_rigid_data_to_*_model system tests.

The frame_order.num_int_pts user function call was changed to frame_order.sobol_setup.

Renamed all the Frame_order.test_num_int_pts* system tests to Frame_order.test_sobol_setup*.

These system tests where for checking the operation of the old frame_order.num_int_pts user
function. But this is now the frame_order.sobol_setup user function.

Renamed the cdp.used_sobol_points variable to sobol_points_used.

This is created by the count_sobol_points() frame order function. The name change is to match the
sobol_max_points and sobol_oversample variable names.

Updates to all of the Frame_order.test_count_sobol_points_* system tests.

The frame_order.sobol_setup user function is used to set a small maximum number of points (20) to
allow the tests to be fast. The value of 20 is also checked for to allow the tests to pass.

Added a backwards compatibility hook for state and results files for the Sobol' sequence changes.

The data pipe num_int_pts variable is now renamed to sobol_max_points when present, and the
sobol_oversample variable is created and set to 1.

Fixes for the Frame_order.test_count_sobol_points2 system test.

The test_suite/shared_data/frame_order/axis_permutations/cam_pseudo_ellipse.bz2 relax state file has
been manual edited to change the num_int_pts data pipe structure to sobol_max_points and to add the
new sobol_oversample variable.

Updated the Frame_order.test_count_sobol_points system test.

The call to the frame_order.num_int_pts user function was changed to
frame_order.sobol_setup.

Updated the Frame_order.test_auto_analysis system test script.

This now uses the new auto-analysis Optimisation_settings object design.

Created the sobol_setup() method for the frame order auto-analysis.

This is used to correctly handle the new design of the frame_order.sobol_setup user function
consistently throughout the protocol.
