Created the Mf.test_bug_20531_molmol_macro_write_relaxfault system test.
This is an attempt at catching bug #20531. It creates all of the m0-m9 and tm0-tm9 models, sets
some parameter values, and then attempts to create all of the Molmol macros, PyMOL macros, Grace
plots and parameter text files as present in the auto_analysis.dauvergne_protocol module.
