Created the Bmrb.test_bug_22703_display_empty system and GUI test.

This system test catches bug #22703 (https://gna.org/bugs/?22703), the failure of the bmrb.display
user function with an AttributeError when no data is present.

It is simultaneously a system and GUI test, as the GUI test class inherits directly from the system
test class.

Added a section printout to the frame order auto-analysis when summary tables are created.

The verbosity flag is now being respected by the frame order specific API calculate() method.

This silences the method when executing the dx.map user function. The chi2 value printout is
suppressed and the verbosity argument is being sent into the frame order count_sobol_points()
function.

Fix for the frame order specific API calculate() method.

This was caught by the Frame_order.test_opendx_map system test. The scaling matrix was not being
specified by the dx.map user function backend and this was causing the method to fail. Instead of
passing the non-existent scaling matrix into the target function, the argument is simply ignored.
The scaling matrix has no effect on the minimise.calculate user function so it is not necessary.

Upgraded the Frame_order.test_opendx_map system test.

To upgrade from the ancient design to the current design so that the test is functional and
relevant, this now uses the same setup as the Frame_order.test_cam_qr_int_rigid user function.
Instead of performing optimisation, the test calls the dx.map user function.

Renamed the Frame_order.fixme_test_opendx_map system test to Frame_order.test_opendx_map to activate it.

Updated the test_suite.system_tests.scripts.frame_order package __all__ list.

Elimination of most of the Frame_order.fixme_test_* system tests and associated data.

These tests are from a very early stage of the development of the frame order theory back when the
base data was the full and reduced alignment tensors for the each domain calculated from the RDC
data. They do not fit into the current analysis where the base data is the RDCs and PCSs for the
moving domain. There is no point upgrading the tests as it will be far too much effort and it will
only duplicate the coverage of the Frame_order.test_cam_* system tests.

Expanded the frame order auto-analysis documentation.

This adds a description for the summarise() and count_sobol_points() functions.

Fixes for the auto_analyses.frame_order.summerise() function.

If the count_sobol_points() function is called followed by summerise(), a RelaxError will be raised
as the data pipe already exists. The summerise() function has been modified to switch to the data
pipe if it already exists.
