Modified the Bmrb.test_bug_22703_display_empty system/GUI test to catch the RelaxNoFrqError.

The model-free bmrb_write() API method now checks for spectrometer information.

This is via a call to the pipe_control.spectrometer.check_spectrometer_setup() function.

Fix for a broken elif block in the new pipe_control.spectrometer.check_spectrometer_setup() function.

The frame_order.simulate user function now defaults to creating a gzipped PDB file.

This is to save room, and because most molecular viewers will automatically read gzipped PDB files.

Renamed the pipe_control.spectrometer.check_setup() function to check_spectrometer_setup().

This is so it can be used without confusion outside of the module.

Created the RelaxNoFrqWarning warning class for warning that no spectrometer information is present.

Created the pipe_control.spectrometer.check_setup() function.

This follows the design on the wiki page http://wiki.nmr-relax.com/Relax_source_design.

This is for checking if spectrometer information has been set up.

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.
