More fixed for the frame order count_sobol_points() function.

The torsion angle for the torsionless models is no longer accessed, and the cone_theta parameter is
only accessed for models with this parameter.

Fix for the frame order count_sobol_points() function.

The free-rotor isotropic cone model was incorrectly handled, as the cone parameter is 'cone_s1' and
not 'cone_theta'. The order parameter is now converted to angle before checking if the Sobol' point
is outside of the cone or not.

Fix for the frame order count_sobol_points() function.

The checks for the model, parameter and domain set up must come first, before cdp.model is accessed.
Otherwise the frame_order.num_int_pts user function will often fail.

Updated the number of points in the Frame_order.test_count_sobol_points_free_rotor system test.

This is to allow the test to pass.

Fix for the frame_order.count_sobol_points user function for the free-rotor models.

The torsion angle is now correctly handled as the 3 free-rotor models do not have cdp.cone_sigma_max
set.

Created the Frame_order.test_count_sobol_points_free_rotor system test.

This is to demonstrate that the frame_order.count_sobol_points user function currently fails for the
free-rotor model.

The frame order count_sobol_points() function is now being called by all of minimise user functions.

This occurs at the end of the minimise.calculate, minimise.grid_search, and minimise.execute user
function backends to provide more feedback to the user as to the quality of the optimisation. To
avoid initialising the target function twice, the count_sobol_points() function now accepts the
initialised target function as an optional argument.

Updated the number of points to allow the Frame_order.test_count_sobol_points_rotor system test to pass.

Fix for the frame_order.count_sobol_points user function for the rotor model.

The sigma angles unpacking required a dimensionality collapse in the Sobol' angle data structure.

Created the Frame_order.test_count_sobol_points_rotor system test.

This is to test the frame_order.count_sobol_points user function for the rotor model.
