Updated the Frame_order.test_count_sobol_points2 system test for the correct number of Sobol' points.

Created the frame_order.count_sobol_points user function.

This is simply a frontend to the new specific_analyses.frame_order.optimisation.count_sobol_points()
function.

Created the Frame_order.test_count_sobol_points2 system test.

This checks the operation of the frame_order.count_sobol_points user function. As this user
function has not been implemented yet, the test currently fails.

Modified the Frame_order.test_count_sobol_points system test.

The number of points has been massively decreased as generating Sobol' points takes a long time, and
the check for the number of used Sobol' points has been set to the real value.

Implementation of the specific_analyses.frame_order.optimisation.count_sobol_points() function.

This is used by the frame_order.num_int_pts user function to provide a printout of the number of
Sobol' integration points used for the current parameter values. This is to provide user feedback
so that it is know if enough Sobol' points have been used.

Created the Frame_order.test_count_sobol_points system test.

This will test that the frame_order.num_int_pts user function can correctly count the number of
Sobol' integration points used for the current set of parameter values. This
frame_order.num_int_pts functionality does not exist yet.

Created the Frame_order.test_num_int_pts3 system test.

This checks the operation of the frame_order.num_int_pts user function when the model has been and
the frame order parameters have been set up.

Created the check_parameters() function for the frame order analysis.

This is in the specific_analyses.frame_order.checks module. The function checks that the frame
order parameters have been set up and have values.

The frame_order.ref_domain user function backend now uses the check_domain() function.

Fixes for the new check_domain() and check_model() frame order functions.
