Renamed functions (get_first_reference_line_numeration_marker_patterns_via_brackets,..via_dots and ..via_numbers. The 2 latter are tried ONLY when the get_first_reference_line_numeration_marker_patterns_via_brackets fails to find any reference section, and ..via_numbers only if ...via_dots fails. Whilst these additional searches are useful they find a certain amount of rubbish. The variable how_found_start indicates the method of finding the reference section (0=by title, 1 no title via_brackets, 2 no title via_dots and 3 no title via_numbers (the weakest..). Then if NO reports and NO journal titles are found and how_found_start > 2; all results (very often complete nonsense in terms of references) are discarded. This functionality was actually introduced in the previous version - this version is only about better naming conventions..
