Removal of debugging code that was accidentally deleted.

Missing imports for the lib.frame_order.matrix_ops module.

These are for the recently restored SciPy quadratic integration functions.

Updated all of the Scipy quadratic integration frame order target functions.

A number of the data structures in the target function class have been redesigned since these target
functions were deleted back in May. All of the func_*_quad_int*() target functions have been
updated for these changes.

Turned off optimisation for all of the Frame_order.test_cam_quad_int_* system tests.

The SciPy quadratic integration is far too slow to be used in the test suite. The simple call to
the minimise.calculate user function is sufficient for checking these target functions.

The Sobol' point counting is now turned off for the frame order optimisation functions if none exist.

If the cdp.quad_int flag is set, then there will be no Sobol' points to count. This
count_sobol_point() user feedback function will therefore not be called by the minimise.calculate,
minimise.grid_search and minimise.execute user functions.

Missing imports for the SciPy quadratic integration function for the PCS in lib.frame_order.rotor.

Updated all of the SciPy quadratic integration frame order target functions.

The pivot point is now handled quite different from back in May when these functions were deleted.

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

This test is not normally run as it blacklisted and duplicates the coverage of other tests. However
its chi-squared value check had not been updated for a while and hence the test fails when
explicitly run.

Activated the quad_int flag for a number of the Frame_order.test_cam_quad_int_* system tests.

The quad_int argument for the flags() test suite method had been missed for a few of these tests.

Duplicated all Frame_order.test_cam_* system tests for testing the SciPy quadratic integration.

The Frame_order.test_cam_* system tests have all been renamed to Frame_order.test_cam_qr_int_*.
These have been duplicated and renamed to Frame_order.test_cam_quad_int_*. The flag() system test
method has been extended to include the quad_int flag which is then stored in the status object and
used in the base CaM frame order system test script to activate the frame_order.quad_int user
function.
