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

This is in the specific_analyses.frame_order.checks module. The function checks that the frame
order model has been selected via the frame_order.select_model user function.

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

This is in the specific_analyses.frame_order.checks module. The function checks that the reference
domain has been specified.

Renamed the Frame_order.test_num_int_points system test to Frame_order.test_num_int_pts.

Created the Frame_order.test_num_int_pts2 system test.

This checks the operation of the frame_order.num_int_pts user function when only the model has been
chosen.

Created the very simple Frame_order.test_num_int_points system test.

This simply creates a data pipe and calls the frame_order.num_int_pts user function to test its
operation. This is to increase the test suite coverage of this user function.

Alphabetical ordering of most of the Frame_order system tests.

Small speed up of the Frame_order.test_auto_analysis system test.

Modified the Frame_order.test_pseudo_ellipse_zero_cone_angle system test to be quick.

Now that the test passes, the optimisation needs to be short. So a maximum of two iterations are
now set. Otherwise the test would take hours to complete.

Updates for all of the Frame_order.test_axis_perm_* system tests.

The axis permutations and angle permutations are now performed correctly within the tests
themselves. This allows the tests to pass.

Fix for the Pseudo_elliptic cone object for when the cone angles are zero.

The Pseudo_elliptic.phi_max() method now avoids a divide by zero error.
