Clean up of the gui_bieri.res.results_analysis module (much code deletion)
This corresponds to one component of the patch_II file attached to https://gna.org/task/?6847 by
Michael Bieri (https://gna.org/users/michaelbieri).
This code appears to have been an unnecessary duplication of that in other modules. It looks like a
remnant of the splitting up of relax_gui.py at revision r10085.
