How to use the refextract.references.regexs.get_reference_section_title_patterns function in refextract

def test_reference_section_title_pattern():
    r = regexs.get_reference_section_title_patterns()
    assert len(r) > 2

{ 'start_line' : (integer) - index in docbody of 1st reference line,
          'title_string' : (string) - title of the reference section.
          'marker' : (string) - the marker of the first reference line,
          'marker_pattern' : (string) - regexp string used to find the marker,
          'title_marker_same_line' : (integer) - flag to indicate whether the
                                        reference section title was on the same
                                        line as the first reference line's
                                        marker or not. 1 if it was; 0 if not.
        }
        Much of this information is used by later functions to rebuild
        a reference section.
         -- OR --
                (None) - when the reference section could not be found.
