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.

Fix for the rigid frame order model for the recent frame_order.sobol_setup user function changes.

For this model, the number of Sobol' points normally is does not exist. This is now correctly
handled.

Converted the frame order auto-analysis to use the new frame_order.sobol_setup user function design.

The auto-analysis Optimisation_settings object has also been modified so that all num_int_pts
arguments and internal structures have been split into the two new sobol_max_points and
sobol_oversample names and objects.

Changed the default oversampling factor from 100 to 1 in the frame_order.sobol_setup user function.

Updated all the lib.frame_order.*.pcs_numeric_int_*() functions for the new Sobol' point algorithm.

The functions now all accept the max_points argument and terminate the loop over the Sobol' points
once the maximum number of points has been reached. The calls to numpy.swapaxes() have also been
removed as this is now pre-performed by the target function initialisation.

Updated the frame order count_sobol_points() function to use the new Sobol_data container.

The Sobol' sequence data generated by the target function is now located at
target_functions.frame_order.sobol_data.
